Description Usage Arguments Value
Calculate the conditional likelihood for the univariate and bivariate sampling cases across all subjects (Keep.liC=FALSE) or the subject specific contributions to the conditional likelihood along with the log-transformed ascertainment correction for multiple imputation (Keep.liC=TRUE).
1 2 |
y |
response vector |
x |
sum(n_i) by p design matrix for fixed effects |
z |
sum(n_i) by q design matrix for random effects |
w.function |
sum(n_i) vector with possible values that include "mean" "intercept" "slope" and "bivar." There should be one unique value per subject |
id |
sum(n_i) vector of subject ids |
beta |
mean model parameter p-vector |
sigma.vc |
vector of variance components on standard deviation scale |
rho.vc |
vector of correlations among the random effects. The length should be q choose 2 |
sigma.e |
std dev of the measurement error distribution |
cutpoints |
A matrix with the first dimension equal to sum(n_i). These cutpoints define the sampling regions [bivariate Q_i: each row is a vector of length 4 c(xlow, xhigh, ylow, yhigh); univariate Q_i: each row is a vector of length 2 c(k1,k2) to define the sampling regions, i.e., low, middle, high]. Each subject should have n_i rows of the same values. |
SampProb |
A matrix with the first dimension equal to sum(n_i). Sampling probabilities from within each region [bivariate Q_i: each row is a vector of length 2 c(central region, outlying region); univariate Q_i: each row is a vector of length 3 with sampling probabilities for each region]. Each subject should have n_i rows of the same values. |
Weights |
Subject specific sampling weights. A vector of length sum(n_i). Not used unless using weighted Likelihood |
Keep.liC |
If FALSE, the function returns the conditional log likelihood across all subjects. If TRUE, subject specific contributions and exponentiated subject specific ascertainment corrections are returned in a list. |
If Keep.liC=FALSE, conditional log likelihood. If Keep.liC=TRUE, a two-element list that contains subject specific likelihood contributions and exponentiated ascertainment corrections.
