Multiple Imputation: A Righteous Approach to Handling Missing Data
 
59:34
It will sound like cheating, but it isn't. It's so righteous dude! Multiple imputation (MI) is an effective and responsible way to handle data which is missing at random (MAR). You'll find out what that means too... Please join Elaine Eisenbeisz, Owner and Principal of Omega Statistics, as she presents an overview of MI concepts. (Original Air Date: August, 2014)

Statistical Methods for Bias Adjustment, "Analysis of Missing Data" Professor Takahiro Hoshino
 
03:26
Title:Statistical Methods for Bias Adjustment, "Analysis of Missing Data" Professor Takahiro Hoshino, Department of Economics, Keio University My focus research topics are statistical causal inference and its applications. You may not be familiar with the term "causal inference," so let me give you an example. Let's say we want to find out which is the better way to treat a certain illness: medication or surgery. As a result of investigation, of the two groups, one medicated and one having had surgery, is it reasonable to conclude that surgery is the better approach to treatment in cases where it offers a far higher survival rate? If only patients in good overall condition with no complications can undergo surgery, while many patients in poor condition with complications cannot, it may seem that the difference between the survival rates for medication and surgery may be due to the difference in the baseline condition of the patient. If a patient who has undergone surgery could have also been cured by medication, perhaps medication would be a better approach to treatment than placing a heavy burden on the body with surgery. 【True effects cannot be understood by simple comparison】---------------------------------- The same can also be said of verification of the effects of costly TV advertisements (TV Ads). In fact, a comparison of two groups, one which has seen a TV Ad for a game application and one which has not, reveals what first seems to be the opposite effect to the one intended, where the group that has seen the TV Ad used the application for less time and opened the application less times than the group that has not seen the TV Ad. However, the group that has not seen the TV Ad spends more time using smartphones than watching TV, so actually, the result is natural. Really, the proper evaluation index is "how much application usage time would be decreased if the group that saw the TV Ad had not seen it." "Usage time had not seen it" is a missing value, known by the term "potential outcome,". Therefore analysis needs to be performed, factoring in this so-called potential outcome. Looking at almost all problems in society, true effects cannot be obtained by simple comparison in areas such as evaluation of policies in economics, evaluation of marketing measures and the effects of teaching methods. My research on related to the development and application of methodology for the performance of correct policy evaluation and statistical causal effect received the Japan Society for the 13th Promotion of Science Prize and Japan Statistical Society Research Achievement Award. 【The analysis of missing data that handles data that cannot be observed】------------------- Statistical causal inference is one of important fields in missing data analysis that deals with unobservable data that we considered earlier, such as potential "usage time". Recently, decreasing accuracy of government statistics has become problematic and this has led to calls for development of new indices that combine data from government surveys with big data acquired by companies. However, because big data is missing data which is biased in that it contains only "in-house purchasing and behavior logs" of a company's own customers, I am working with the Statistics Bureau of the Ministry of Internal Affairs and Communications on the development of new indices that incorporate big data with bias corrected. No matter how much big data is acquired, because bias that exists in the data may yield incorrect results, The development and application of missing data analysis and statistical data fusion methods are becoming ever-more important in fields such as academic research, government decision-making and corporate marketing practices. http://www001.upp.so-net.ne.jp/bayesian/Eindex.html
Webinar: Approaches to Missing Data--The Good, the Bad, and the Unthinkable
 
01:05:53
Published on 12/1/2016 Presented on 12/1/2016 Presented by Karen Grace-Martin You’ve probably heard about many different approaches to dealing with missing data, and you’ve probably gotten different opinions about which one you should use. In this webinar, you’ll get an overview of: • the three types of missing data, and how they affect the approach to take • the common approach that is generally worse than any other • the easy, common, seemingly bad approach that often isn’t so bad, and the situations when it doesn’t work • the two approaches that give unbiased results, one that is very easy to implement, but only works in limited situations, and one that is harder to implement well, but works with any statistical analysis.

Learn more about credit risk modeling in R: https://www.datacamp.com/courses/introduction-to-credit-risk-modeling-in-r Now, we have removed the observation containing a bivariate outlier for age and annual income from the data set. What we did not discuss before is that there are missing inputs (or NA's, which stand for not available) for two variables: employment length and interest rate. In this video we will demonstrate some methods for handling missing data on the employment length variable. You'll practice this newly gained knowledge yourself on the variable interest rate. First, you want to know how many inputs are missing, as this will affect what you do with them. A simple way of finding out is with the function summary(). If you do this for employment length, you will see that there are 809 NA's. There are generally three ways to treat missing inputs: delete them, replace them, or keep them. We will illustrate these methods on employment length. When deleting, you can either delete the observations where missing inputs are detected, or delete an entire variable. Typically, you would only want to delete observations if there is just a small number of missing inputs, and would only consider deleting an entire variable when many cases are missing. Using this construction with which() and is.na(), the rows with missing inputs are deleted in the new data set loan_data_no_NA. To delete the entire variable employment length, you simply set the employment length variable in the loan data equal to NULL. Here, we save the result to a copy of the data set called loan_data_delete_employ. Making a copy of your original data before deleting things can be a good way to avoid losing information, but may be costly if working with very large data sets. Second, when replacing a variable, common practice is to replace missing values with the median of the values that are actually observed. This is called median imputation. Last, you can keep the missing values, since in some cases, the fact that a value is missing is important information. Unfortunately, keeping the NAs as such is not always possible, as some methods will automatically delete rows with NAs because they cannot deal with them. So how can we keep NAs? A popular solution is coarse classification. Using this method, you basically put a continuous variable into so-called bins. Let's start off making a new variable emp_cat, which will be the variable replacing emp_length. The employment length in our data set ranges from 0 to 62 years. We will put employment length into bins of roughly 15 years, with groups 0 to 15, 15 to 30, 30 to 45, 45 plus, and a "missing” group, representing the NAs. Let's see how this changes our data. Let's look at the plot of this new factor variable. It appears that the bin '0-15' contains a very high proportion of the cases, so it might seem more reasonable to look at bins of different ranges but with similar frequencies, as shown here. You can get these results by trial and error for different bin ranges, or by using quantile functions to know exactly where the breaks should be to get more balanced bins. Before trying all of this in R yourself, let me finish the video with a couple of remarks. First, all the methods for missing data handling can also be applied to outliers. If you think an outlier is wrong, you can treat it as NA and use any of the methods we have discussed in this chapter. Second, you may have noticed I only talked about missingness for continuous variables in this chapter. What about factor variables? Here's the basic approach. For categorical variables, deletion works in the exact same way as for continuous variables, deleting either observations or entire variables. When we wish to replace a missing factor variable, this is done by assigning it to the modal class, which is the class with the highest frequency. Keeping NAs for a categorical variable is done by including a missing category. Now, let's try some of these methods yourself!

Frequency analysis of Rainfall/Flood data | Hydrology | CE
 
41:20
Real Life Application Frequency analysis plays an important role in hydraulic engineering applications such as those concerned with floods, for example in construction of Dams it is necessary to find out the probability of occurring an extreme flood. Explanation To understand the concept with clarity it’s important to understand two things:- 1. Probability 2. Return Period With the basic concept of probability we know that probability of any event is given as Favorable cases by total number of cases. Return Period also called as Recurrence Interval or Frequency (T) is the time period on an average after which peak flood discharge is likely to be equaled or exceeded. In order to find the Return Period Plotting Position method is used, in this method the given data is arranged in decreasing order of magnitude and accordingly rank(m) is assigned to each value. The return period for any value is then calculated by following three methods:- California Formula Weibull’s Formula Hazens Formula Then the probability that a particular value is equal or exceeded is then given by- Probability=1/T, where T is the Return Period. We make use of Binomial Event for calculating probability, Binomial even is an event which has only two possible outcomes and is suited for this analysis also as either flood can occur or flood cannot occur. We calculate the probability that a particular event (having probability p) happens exactly r times out of n trials. The probability of Reliability and Risk is important for us considering the design of hydraulic structures. Reliability: This is the probability that a particular flood magnitude is never equaled or exceeded in the design life of structure. Risk: This is the probability that a particular flood magnitude is equaled or exceeded at least once in the design life of structure.

Much of the work involved in analyzing data resides in importing, cleaning and transforming data in preparation for analysis. Therefore, the first half of the course is comprised of a 2-part overview of basic and intermediate Pandas usage that will show how to effectively manipulate datasets in memory. This includes tasks like indexing, alignment, join/merge methods, date/time types, and handling of missing data. Next, we will cover plotting and visualization using Pandas and Matplotlib, focusing on creating effective visual representations of your data, while avoiding common pitfalls. Finally, participants will be introduced to methods for statistical data modeling using some of the advanced functions in Numpy, Scipy and Pandas. This will include fitting your data to probability distributions, estimating relationships among variables using linear and non-linear models, and a brief introduction to Bayesian methods. Each section of the tutorial will involve hands-on manipulation and analysis of sample datasets, to be provided to attendees in advance. The target audience for the tutorial includes all new Python users, though we recommend that users also attend the NumPy and IPython session in the introductory track.
