There programs are very useful for simple statistical tests.

t_confidence_interval calculates the confidence interval of the t-distrubution, with one or two tails, a given confidence level, number of degrees of freedom, along a specified dimension of the input array.

function calculates the probability density function for the t-ditribution.

t_distrib calculates the t-distribution and the cumulative probability function for the t-distribution and makes a plot.

t_alpha calculates the significance level alpha given a t-statistic.

t_table calculates a Table of statistics for the t-distribution.

t_icpbf is the inverse cumulative probability function for the t-distribution. It calculates the t-statistic given the level of significance alpha and nu degrees of freedom.

t_mean_num_obs calculates the number of required observations to achieve the desired level of significance.
