• average deviation and median average deviation (MAD)

• skew and kurtosis

• standard error of the mean

Multivariate statistics:

• Pearson’s correlation coefficient

• Q-correlation coefficient

• covariance (sample and population)

• linear regression

• sums Sxx, Syy and Sxy

and others.

Requires Python 3.1 or better.
