Detailed Description

A class to compute statistics from homoscedastic using a fixed General Linear Model. This class produces a statistic per effect of interest: t-statistic for t-tests, sqrt(F-statistic) for F-tests. It should be used in cases where:

  • the same design matrix is to be applied for all image elements being tested (it is thus able to pre-compute a number of matrices before testing, improving execution speed);
  • When the data are considered to be homoscedastic; that is, the variance is equivalent across all inputs.
