.TH "PSIGNIFIT" "1" "August 26, 2005" "Michael Hanke" "" .SH "NAME" \fBPsignifit\fR \- A program for fitting and testing hypotheses about psychometric functions. .SH "DESCRIPTION" \fBPsignifit\fR 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. .br \fBPsignifit\fR performs the calculation of confidence intervals as well as goodness\-of\-fit tests. \fBPsignifit\fR accepts input in a number of different ways: .IP "From named text files:" \fBpsignifit\fR .PP .IP "Entirely from the console:" \fBpsignifit\fR (...) .br (enter data and preferences from the console and then send an EOF character \- Ctrl\-D in most UNIX shells) .PP .IP "Partly from named text files, partly from the console:" \fBpsignifit\fR \- .PP .IP "Through a pipe:" \fBcat\fR | \fBpsignifit\fR .PP .IP "Or via a mixture of piped input on stdin and files named on the command line:" \fBecho\fR "#random_seed 12345" | \fBcat\fR | \fBpsignifit\fR \- .PP For more documentation see the files in the .I /usr/share/doc/psignifit directory or visit .I http://bootstrap\-software.org/psignifit/ .SH "EXAMPLES" An example dataset and fitting preferences can be found in .I /usr/share/doc/psignifit/examples .SH "TEST" A regression test for \fBpsignifit\fR can be found in .I /usr/share/doc/psignifit/tests . .SH "AUTHOR" \fBPsignifit\fR was written by Jeremy Hill. .PP This manual page was written by Michael Hanke , for the Debian project (but may be used by others).
