ANOVA (Analysis of Variance) is an analysis tool used to see the effect of categorical independent variables on a dependent variable in regressions. There are two main assumptions that need to be met when using ANOVA. To explore how to perform ANOVA in Stata, we will use Stata’s reading scores dataset (‘reading.dta’). This dataset can …

The purpose of the inlist command in Stata is to determine if a particular argument belongs to a specific list. It allows the user to use multiple conditions or multiple values in the condition. Let’s explain this with the help of an example. We will use the example dataset provided by Stata itself. Use the …
When the new dataset is imported or generated, you may discover that the variable names do not correspond to your task. Perhaps they do not correspond to the variables in another dataset you wish to merge. In such a situation, rename commands help in resolving this issue. The Rename command is used to rename variable …

This article discusses how to perform multiple regression in Stata and how to deal with the results that are obtained. Unlike simple regressions that only have a single independent variable, multiple regressions have more than one independent variable. Let’s start by loading Stata’s built-in auto dataset into Stata’s memory. To run a multiple regression from …
Often times, we have to work with categorical variables when doing statistical analysis. Categorical variables are those variables that have two or more categories or groups. For example, a variable representing sectors in a stock market could have categories like tech, automobiles, pharmaceuticals, cement, banks etc. These categories of string type may also be needed …
