Methods for statistical tests Detailed Description
Function Documentation
get critical value of a Student-T distribution for a given number of degrees of freedom at a confidence level
compute a t-value for the hypothesis that x and y are from the same population; Assuming that x and y represent normally distributed random samples with equal variance, the returned value comes from a Student-T distribution with countx + county - 2 degrees of freedom; this value can be compared with a critical value (see also SCIPstudentTGetCriticalValue()) at a predefined confidence level for checking if x and y significantly differ in location
returns the value of the Gauss error function evaluated at a given point
get critical value of a standard normal distribution at a given confidence level
calculates the cumulative distribution P(-infinity <= x <= value) that a normally distributed random variable x takes a value between -infinity and parameter The distribution is given by the respective mean and deviation. This implementation uses the error function erf().
