Before you start with modeling in Stata, you need to check distributions of data and conduct some statistical tests on the data. There are various tests that you need in order to conduct and perform operations as far as data distributions are concerned; this will help you understand the data better and create better models.

Here are some of the topics that we will cover in this chapter:
