Purpose
Evaluates t-distribution and its inverse.
Synopsis
- y = ttestp(x,a,z)
Description
Evaluates a t-distribution with input flag z. For z = 1 the output y is the probability point for given t-statistic x with a degrees of freedom. For z = 2 the output y is the t-statistic for given probability point x with a degrees of freedom.
Examples
y = ttestp(1.9606,5000,1)
y = 0.025
y = ttestp(0.005,5000,2)
y = 2.533
