PROGRAM:
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> -
