Fitting and testing hypotheses about psychometric functions
Psignifit allows fitting of psychometric functions to datasets while maintaining full control over a large number of parameters. Data can either be read from text files or passed through a pipe.
Psignifit performs the calculation of confidence intervals as well as goodness-of-fit tests.
This is the command line version.
Please note: This is the legacy version 2.x of psignifit.
