weibull_link: Weibull link function with guessing and lapsing rates

Description

Weibull link for use with GLM functions. The guessing rate and lapsing rate are fixed, and power parameter is set to be equal K, hence link is a function of only one variable

Usage

weibull_link( K, guessing = 0, lapsing = 0 )

Arguments

K

power parameter for reverse Weibull link function

guessing

guessing rate; default is 0

lapsing

lapsing rate; default is 0

Value

link

Weibull 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<-weibull_link( 20 )
fit <- glm( glmformula, data = glmdata, weights = m, family = binomial( userlink ) )
