    """A Collection of Efficient and Extremely Fast R Functions.

    A collection of fast (utility) functions for data analysis. Column- and
    row- wise means, medians, variances, minimums, maximums, many t, F and
    G-square tests, many regressions (normal, logistic, Poisson), are some of
    the many fast functions. References: a) Tsagris M., Papadakis M. (2018).
