Stata 15 help for mi_estimation

[MI] estimation -- Estimation commands for use with mi estimate

Description

Multiple-imputation data analysis in Stata is similar to standard data analysis. The standard syntax applies, but you need to remember the following for MI data analysis:

1. The data must be declared as mi data.

If you already have multiply imputed data (saved in Stata format), use mi import to import it into mi.

If you do not have multiply imputed data, use mi set to declare your original data to be mi data and use mi impute to fill in missing values.

2. After you have declared mi data, commands such as svyset, stset, and xtset cannot be used. Instead use mi svyset to declare survey data, use mi stset to declare survival data, and use mi xtset to declare panel data. See [MI] mi XXXset.

3. Prefix the estimation commands with mi estimate:.

The following estimation commands support the mi estimate prefix.
