probit_link: Probit link function with guessing and lapsing rates

Description

Probit link for use with GLM functions. The guessing and lapsing rate are fixed to values given in lims, hence link is a function of only one variable

Usage

probit_link( guessing = 0, lapsing = 0 )

Arguments

guessing

guessing rate; default is 0

lapsing

lapsing rate; default is 0

Value

• link
  Probit link for use in all GLM functions

Examples

data( "01_Miranda" )
x <- example01$x
r <- example01$r
m <- example01$m
glmdata <- data.frame( cbind( r/m ,m , x ) )
names( glmdata ) <- c( "resp", "m", "x" )
glmformula <- c( "resp ~ x" )
userlink<-probit_link( 0.1, 0.1 )
fit <- glm( glmformula, data = glmdata, weights = m, family = binomial( userlink ) )
