Setting Options for Fitting Gaussian Copula Marginal Regression Models

Sets options that affect the fitting of Gaussian copula marginal regression models.

Keywords
regression, nonlinear
Usage
gcmr.options(seed = round(runif(1, 1, 1e+05)), nrep = c(100, 1000), 
    no.se = FALSE, method = c("BFGS", "Nelder-Mead", "CG"), ...)
Arguments
seed

seed of the pseudorandom generator used in the importance sampling algorithm for likelihood approximation in case of discrete responses.

nrep

Monte Carlo size of the importance sampling algorithm for likelihood approximation in case of discrete responses. nrep can be a vector so that the model is fitted with a sequence of different Monte Carlo sizes. In this case, the starting values for optimization of the likelihood are taken from the previous fitting. A reasonable strategy is to fit the model with a small Monte Carlo size to obtain sensible starting values and then refit with a larger Monte Carlo size. The default value is 100 for the first optimization and 1000 for the second and definitive optimization.

no.se

logical. Should standard errors be computed and returned or not?

method

a character string specifying the method argument passed to optim. The default optimization routine is the quasi-Newton algorithm BFGS. See optim for details.

...

arguments passed to optim.

Value

A list containing the options.
