What is a Loop? When we need to perform certain tasks or operations that are repetitive in nature, or where there is a need to run the same kind of command over and over, we use loops. Loops, in Stata, allow us to run a command (or a set of commands) as many times as

This article will go over how we can check the normality of a variable in Stata. Quite often, it is thought necessary for dependent and independent variables in a regression to have a normal distribution. Though sometimes confused with the normality assumption of regression, however, it is the distribution of the error term that is

This article will go over, in detail, about the reshape command in Stata. This article is motivated by Chapter 9 Data Management Using Stata by Michael N. Mitchell. of It is worth starting by looking at why exactly we need to use this command. The first thing we need to understand before diving into reshape

Questionnaire/Survey data is called primary data as it is collected directly by researchers for their study and analysis from the primary sources of interest. When we use data collected by someone else for our analysis, it is called secondary data as it is not obtained directly by ourselves. Download Example File This article will go
