TTESTTABLE: Stata module to compute differences in means by groups including the T-test

Programming Language



ttesttable is a very simple Stata module that performs a mean-comparison test (t-Test) for all possible combinations of groups defined by a variable. For instance, if you have 4 types of observations and you would like to see if there are differences in means between groups, this module computes the t-test for all six possible combinations. The output is presented in a table of differences in means and includes the significance level of the t-test. This table can be exported directly as a LaTeX, HTML or XML file and the underlying matrices are available for further use in Stata.
