Critical Values of the Student's t-distribution

Critical values of the Student's t-distribution with v degrees of freedom for two-sided critical regions.

The Matlab code presented here generates a table (represented as a matrix) with the values of Student's t-distribution with v degrees of freedom (often calculated as the sample size minus one) for a range of two-sided critical regions. The first row represents the confidence levels gamma (the confidence level complements the significance level to unity), the first column represents v, and the numbers in the body of the table are the t-coefficients (as a function of gamma and v). The last row with infinite v gives critical points for a normal distribution (a t-distribution with infinite degrees of freedom is a normal distribution).

The code is based on the theory described in:
