In senhu/FCBMA: Factor collapsing with Bayesian model averaging for regression models

Description

Refit a model based on collapsed factors

Usage

fc.model.refit(varia.list, merge.list, mod)

## S3 method for class 'glm'
fc.model.refit(varia.list, merge.list, mod)

## S3 method for class 'rxGlm'
fc.model.refit(varia.list, merge.list, mod)

## S3 method for class 'lm'
fc.model.refit(varia.list, merge.list, mod)

Arguments

varia.list	a vector of names of factors to be collapsed
merge.list	a list of graycodes, each corresponding to factor in the varia.list
mod	the model to be refitted

Value

A list with the elements

BIC	The BIC value of the refitted model
AIC	The AIC value of the refitted model
logLik	The log-likelihood of the refitted model
model	Details of the refitted model

Examples

data("sweden")
m1 <- glm(Claims ~ Kilometres+Zone+Bonus+Make, offset = log(Insured),
          data = sweden, family = "poisson")
m2 <- fc.model.refit(varia.list=c("Kilometres"),
                     merge.list=list(c(1,2,3,3,4)),
                     mod = m1)
m3 <- fc.model.refit(varia.list=c("Kilometres, Make"),
                     merge.list=list(c(1,2,3,4,5), c(1,2,3,4,5,6,7,8,8)),
                     mod = m1)
