inarmix (version 0.4)

GenerateMixData: Generates simulated data according to a specified INAR mixture model.

Description

This function generates data according to a user-specified INAR mixture model. It returns a data frame which can be used immediately by inarmix.

Usage

GenerateMixData(m, coefs, autocorr, scale=NULL, mix, design.mat, return.labels=F,poisson=F)

Arguments

m

a numeric scalar (the number of subjects)

coefs

a numeric vector

autocorr

a numeric scalar

scale

a numerica scalar

mix

a numeric vector

design.mat

a numeric matrix (the design matrix)

return.labels

an indicator of whether or not to return the class labels

poisson

an indicator of whether or not the data should have marginal Poisson distributions.

Value

A data frame which contains the response and a subject identifier. The other columns contain the data entered from the design.mat argument.

Examples

XX <- cbind(rep(1,9),c(0:8)/4)
colnames(XX) <- c("const","time")
coefs <- rbind(c(-.2,0),c(1.2,.3))
autocorr <- c(.2,.2)
scale <- c(1.5,1.5)
mix.prop <- c(.8,.2)

testdat <- GenerateMixData(1000,coefs,autocorr,scale,mix.prop,XX)
