Functions

func MeanAndVar

func MeanAndVar(X *[]float64) (m, v, n float64)

MeanAndVar returns the sample mean, variance and count as float64's.

func Ttest

func Ttest(A, B *[]float64) (p, t, v, am float64)

Ttest performs a Welch's t test and returns p-value, t-value and the degrees of freedom. The p value based on the hypothesis that mean(B)>mean(A). Based on similar code in rf-ace (Apache 2.0, Timo Erkkilä)
