Model-Free Estimation of a Psychometric Function

Description

Local linear estimation of psychometric functions. Provides functions for nonparametric estimation of a psychometric function and for estimation of a derived threshold and slope, and their standard deviations and confidence intervals.

Functions in modelfree (1.2)

binom_weib

Weibull model for the psychometric function
binom_lims

Maximum likelihood parameter estimates for a psychometric function with guessing and lapsing rates
comploglog_link

Complementary log-log link with guessing and lapsing rates Creates a complementary log-log link function; the guessing rate and lapsing rate are fixed, hence link is a function of only one variable.
binomfit_lims

Parameter estimates for a psychometric function with FIXED guessing and lapsing rates
binom_revweib

Reverse Weibull model for the psychometric function
deviance2

Deviance of a psychometric function
bootstrap_ci_sl

Bootstrap confidence interval for the slope of a psychometric function
bootstrap_sd_th

Bootstrap standard deviation for the slope of a psychometric function
bootstrap_sd_sl

Bootstrap standard deviation for the slope of a psychometric function
bootstrap_ci_th

Bootstrap confidence interval for a slope of a psychometric function
threshold_slope

Estimates of threshold and slope for a fitted psychometric function
locglmfit

Local polynomial estimator of a psychometric function
logit_link

Logit link with guessing and lapsing rates Creates a complementary logit link function; the guessing rate and lapsing rate are fixed, hence link is a function of only one variable.
loglog_link

Log-log link with guessing and lapsing rates
probit_link

Probit link with guessing and lapsing rates
Schofield_etal

Induction of a visual motion aftereffect
Baker_etal

Auditory detection of a gap in noise
bandwidth_bootstrap

Bootstrap bandwidth for local polynomial estimator of a psychometric function
bandwidth_plugin

Plug-in bandwidth for local polynomial estimator of a psychometric function
bandwidth_cross_validation

Cross-validation bandwidth for local polymnomial estimator of a psychometric function
Xie_Griffin

Discrimination of "porthole" views of natural scenes
Carcagno

Discrimination of pitch
Nascimento_etal

Discrimination of image approximations
