I believe this might be interesting for the few that didn't read it
on cvnet already.

> Dear colleagues,
>
> We are pleased to announce the launch of Palamedes, a free toolbox of
> Matlab routines for the analysis of psychophysical data.
>
> Features include:
>
> -Maximum Likelihood fitting of Psychometric Functions (PF), with the
> unique feature of simultaneous multi-condition fitting of PFs:
> Palamedes allows one to fit PFs to several data sets simultaneously
> while allowing flexible control over parameters to define custom
> models. Just to give one example (but many more possibilities exist):
> Palamedes can fit individual thresholds to multiple conditions of an
> experiment while constraining the lapse rate to be equal between
> conditions (giving the obvious advantage of obtaining more reliable
> lapse rate estimates).
>
> -Bayesian PF fitting.
>
> -Maximum Likelihood Difference Scaling (includes generation of
> stimulus sets, simulation of experimental data, data analysis)
>
> -Parametric and Non-parametric Bootstrapping
>
> -Signal Detection Measures (for a wide variety of tasks)
>
> -Goodness-of-fit tests (including Goodness-of-fit of multi-
> condition PF fits)
>
> -Statistical Model Comparisons (e.g., "do thresholds differ
> significantly between experimental conditions?" or even: "do
> thresholds vary as a linear function of, say, adaptation duration or
> is that accelerating/decelerating trend in the data 'real'?").
>
> -Adaptive Methods (up/down, best PEST, QUEST, Psi Method).
>
> All user-end routines include elaborate help comments, including
> example code that will execute when typed into command window. Also
> provided is a set of heavily commented demonstration scripts which
> guide the user through all of the major analyses.
>
> The Palamedes toolbox requires basic Matlab only, no additional
> toolboxes are required. The toolbox is compatible with older versions
> of Matlab (going back to at least release 14 [2004], and likely
> much further).
>
> Palamedes can be downloaded at no cost here:
