Functions for analyzing psychophysical functions

Description

An assortment of functions that could be useful in analyzing data from pyschophysical experiments. It includes functions for calculating d' from several different experimental designs, links for mafc to be used with the binomial family in glm (and possibly other contexts) and a self-Start function for estimating gamma values for CRT screen calibrations.

Details

For the moment, the package contains several functions for calculating d' for a variety of psychophysical paradigms, some link functions for the binomial family in glm (and perhaps other functions) for fitting psychometric functions from mAFC experiments and a self-Start function for estimating the value of the exponent, gamma, based on the luminance calibration of the three channels of a CRT-like display.
