PSIGNIFIT

NAME

Psignifit − A program for fitting and testing hypotheses about psychometric functions.

DESCRIPTION

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. Psignifit accepts input in a number of different ways:
From named text files:

psignifit <data> <preferences>

Entirely from the console:

psignifit (...)
(enter data and preferences from the console and then send an EOF character − Ctrl−D in most UNIX shells)

Partly from named text files, partly from the console:

psignifit <data> <preferences> −

Through a pipe:

cat <data + preferences> | psignifit

Or via a mixture of piped input on stdin and files named on the command
line:

echo "#random_seed 12345" | cat <preferences> | psignifit <data> −
