Control Parameters for Heteroskedastic Binary Response GLMs

Various parameters that control fitting of heteroskedastic binary response models using hetglm.

Keywords
regression
Usage
hetglm.control(method = "nlminb", maxit = 1000, hessian = FALSE, trace = FALSE, start = NULL, ...)
Arguments
method
characters string specifying the method argument passed to optim.
maxit
integer specifying the maxit argument (maximal number of iterations) passed to optim.
hessian
logical. Should the numerical Hessian matrix from the optim output be used for estimation of the covariance matrix? Currently, this must not be modified.
trace
logical or integer controlling whether tracing information on the progress of the optimization should be produced (passed to optim).
start
an optional vector with starting values for all parameters (including phi).
...
arguments passed to optim.
Details

All parameters in hetglm are estimated by maximum likelihood using optim with control options set in hetglm.control. Most arguments are passed on directly to optim, only start controls how optim is called.

Starting values can be supplied via start or estimated by glm.fit, using the homoskedastic model. Covariances are derived numerically using the Hessian matrix returned by optim.

Value

A list with the arguments specified.
