The digamma function is defined as the logarithmic derivative of the gamma function.
The error function (also called the Gauss error function) is a special function of sigmoid shape which occurs in probability, statistics, materials science, and partial differential equations.
The complementary error function.
The complementary error function with fractional error everywhere less than 1.2 × 10-7.
Test if the arrays x and y have significantly different variances.
The inverse error function.
The inverse complementary error function.
Kendall rank correlation test.
The two-sample KS test for the null hypothesis that the data sets are drawn from the same distribution.
The one-sample KS test for the null hypothesis that the data set x is drawn from the given distribution.
log of the Gamma function.
Pearson correlation coefficient test.
Spearman rank correlation coefficient test.
Given the paired arrays x and y, test if they have significantly different means.
Independent one-sample t-test whether the mean of a normally distributed population has a value specified in a null hypothesis.
Test if the arrays x and y have significantly different means.
true if the data arrays are assumed to be drawn from populations with the same true variance. Otherwise, The data arrays are allowed to be drawn from populations with unequal variances.
