Description

Fit joint mean-covariance models based on ACD.

Usage

1
2
acd_estimation(m, Y, X, Z, W, start, mean, trace = FALSE, profile = TRUE,
  errormsg = FALSE, covonly = FALSE, optim_method = "default")

Arguments

m

an integer vector of numbers of measurements for subject.

Y

a vector of responses for all subjects.

X

model matrix for the mean structure model.

Z

model matrix for the diagonal matrix.

W

model matrix for the lower triangular matrix.

start

starting values for the parameters in the model.

mean

when covonly is true, it is used as the given mean.

trace

the values of the objective function and the parameters are printed for all the trace'th iterations.

profile

whether parameters should be estimated sequentially using the idea of profile likelihood or not.

errormsg

whether or not the error message should be print.

covonly

estimate the covariance structure only, and use given mean.

optim_method

optimization method, choose "default" or "BFGS"(vmmin in R).
