# M_STATS: Stata module to implement interpoint distance distribution analysis

*Pietro Tebaldi*

Statistical Software Components from Boston College Department of Economics

**Abstract:**
M_STATS contains two commands, mstat and mtest, to perform inference based on the M statistic, a statistic used to compare the interpoint distance distribution across groups of observations. The two commands can be used to test the null hypothesis that two groups have the same (spatial) distribution. mstat and mtest return the exact M test statistic. Moreover, mtest executes a Monte Carlo type permutation test, returning the empirical p-value together with its confidence interval.

**Language:** Stata
