Descriptive Statistics in outreg2: Using 'sum(log)' for Specific Variables

This guide demonstrates how to generate descriptive statistics for specific variables in Stata using the 'outreg2' command and the 'sum(log)' option. We will focus on the following variables: 'gap', 'gtp', 'size', 'lev', 'roa', 'labor', 'age', 'indratio', 'cash', 'top1', 'soe', 'olddep', 'avgwage', 'lnpgdp', 'DA', and 'msac'.

Steps:

1. Load your data into Stata.
2. Execute the following command:

outreg2 using 'Descriptive statistics', sum(log) keep(gap gtp size lev roa labor age indratio cash top1 soe olddep avgwage lnpgdp DA msac)  

3. Interpret the results: The output will display descriptive statistics for the selected variables, including the mean, standard deviation, minimum, maximum, and number of observations.

Explanation:

• 'outreg2 using 'Descriptive statistics',' specifies the output file name.
• 'sum(log)' calculates the sum of the natural logarithm of each variable.
• 'keep(gap gtp size lev roa labor age indratio cash top1 soe olddep avgwage lnpgdp DA msac)' limits the output to the specific variables of interest.

This approach allows you to obtain descriptive statistics for a set of variables, conveniently organized into a user-friendly table, ready for analysis and interpretation.
