##### Generating Censored Autoregressive Dataset with Linear Mixed Effects.

This function simulates a censored response variable with autoregressive errors of order p, with mixed effect and a established censoring rate. This function returns the censoring vector and censored response vector.

##### Usage
ARpLMEC.sim(m, x = NULL, z = NULL, nj, beta, sigmae, D1, phi,
p.cens = 0, cens.type = "left")
##### Arguments
m

Number of individuals

x

Design matrix of the fixed effects of order n x s, corresponding to vector of fixed effects.

z

Design matrix of the random effects of ordern x b, corresponding to vector of random effects.

nj

Vector 1 x m with the number of observations for each subject, where m is the total number of individuals.

beta

Vector of values fixed effects.

sigmae

It's the value for sigma.

D1

Covariance Matrix for the random effects.

phi

Vector of length Arp, of values for autoregressive parameters.

p.cens

Censoring level for the process. Default is 0

cens.type

left for left censoring, right for right censoring and interval for interval censoring. Default is left

##### Value

returns list:

cc

Vector of censoring indicators.

y_cc

Vector of responses censoring.
