## S3 method for class 'simplexreg'
predict(object, newdata = NULL, type = c("response", "dispersion"), 
   	na.action, ...)

Arguments

object

fitted model object of class "simplexreg"

newdata

an optional data frame in which to look for variables with which to predict. If omitted, original observations are used.

type

character indicating type of predictions:fitted mean of response ("response") or fitted dispersion parameter("dispersion")

na.action

## fit the model
data("sdac", package="simplexreg")
sim.glm2 <- simplexreg(rcd~ageadj+chemo|age, link = "logit", 
  data = sdac)

data("retinal", package = "simplexreg")
sim.gee2 <- simplexreg(Gas~LogT+LogT2+Level|LogT+Level|Time,
  link = "logit", corr = "AR1", id = ID, data = retinal)  	

## predict the mean
predict(sim.glm2, type = "response")

## predict the dispersion
predict(sim.gee2, type = "dispersion")
