MixedPsy - Statistical Tools for the Analysis of Psychophysical Data
Tools for the analysis of psychophysical data in R. This
package allows to estimate the Point of Subjective Equivalence
(PSE) and the Just Noticeable Difference (JND), either from a
psychometric function or from a Generalized Linear Mixed Model
(GLMM). Additionally, the package allows plotting the fitted
models and the response data, simulating psychometric functions
of different shapes, and simulating data sets. For a
description of the use of GLMMs applied to psychophysical data,
refer to Moscatelli et al. (2012).
