Detecting outliers in count data. Ask Question 19. 16. I have what I naively thought to be a fairly straight forward problem that involves outlier detection for many different sets of count data. Specifically, I want to determine if one or more values in a series of count data is higher or lower than expected relative to the rest of the counts in the distribution. The confounding factor is... Detecting Outliers using Stata As is often the case with Stata, instead of a few big commands with several options, we execute several smaller commands instead.
