The collapse command in Stata is used to create summary variables from an existing dataset. It allows you to aggregate observations within groups, summarizing them into a new dataset. Collapsing a dataset can be useful for creating summary statistics, such as the mean and standard deviation, for ...

"Boolean (yes/no)" in Epidata. But when data was exported to Stata 8.2, the result is very frustrating: <snip> What I need is just a binary variable. Must I have to transform it to numerical variable firstly and then label variables and values again manually? Are there any other ways...
Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it…
to exploit the change in trade policy that has led to a more restrictive trade environment. Third, we use both parent and subsidiary variables in order to disentangle from where the statistical significance of relative (parent-subsidiary) variables comes from. Fourth, the sample period is updated...

We mentioned that delta() is commonly used with %tc timevars because Stata's %tc variables have units of milliseconds. If delta() is not specified and in some model you refer to L.bp, you will be referring to the value of bp 1 ms ago. Few people have data with periodicity of a ...
