{title:Description}

{cmd:ksmirnov2var} performs the Kolmogorov-Smirnov test of the equality of distributions for two variables. 

By contrast, {cmd:ksmirnov} will test the equality of distributions of two groups of one variable.

{cmd:ksmirnov2var} is similar to comparing the means of two variables with {cmd:ttest} {varname:1} == {varname:2}, except {cmd:ksmirnov2var} will compare their distributions.

{cmd:ksmirnov2var} is a wrapper for {cmd:ksmirnov}, so it has the same output and stored results.
