ARpMMEC.sim | R Documentation |
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.
ARpMMEC.sim( m, x = NULL, z = NULL, tt = NULL, nj, beta, sigmae, D, phi, struc = "ARp", order = 1, typeModel = "Normal", p.cens = NULL, n.cens = NULL, cens.type = "left", nu = NULL )
m |
Number of individuals |
x |
Design matrix of the fixed effects of order |
z |
Design matrix of the random effects of order |
tt |
Vector |
nj |
Vector |
beta |
Vector of values fixed effects. |
sigmae |
It's the value for sigma. |
D |
Covariance Matrix for the random effects. |
phi |
Vector of length |
struc |
Correlation structure. This must be one of |
order |
Order of the autoregressive process. Must be a positive integer value. |
typeModel |
|
p.cens |
Censoring percentage for the process. Default is |
n.cens |
Censoring level for the process. Default is |
cens.type |
|
nu |
degrees of freedom for t-Student distibution (nu > 0, maybe non-integer). |
returns list:
cc |
Vector of censoring indicators. |
y_cc |
Vector of responses censoring. |
