Qstats is part of the QTL Cartographer suite of programs.

Qstats does some basic statistics on a dataset of quantitative traits. It plots a histogram and calculates the sample size, mean, variance standard deviation, skewness, kurtosis, and average deviation for a quantitative trait. The program also summarizes missing marker and trait data, as well as determining the marker types. Finally, Qstats will test whether markers are segregating at random.
