A Go library and command for evaluating whether two or more sets of measurements are statistically different. It does this by performing a Student's t-test at a particular confidence level, making it suitable for small sets of measurements (e.g., multiple runs of a benchmark). It's inspired largely by FreeBSD's ministat (written by Poul-Henning Kamp).
