Initialize a glmeStruct Object

DESCRIPTION:

The individual generalized linear mixed-effects model components of the glmeStruct list are initialized.

USAGE:

initialize(object, data, groups, conLin, control)

REQUIRED ARGUMENTS:

object
an object inheriting from class glmeStruct, representing a list of generalized linear mixed-effects model components, such as reStruct, corStruct, and varFunc objects.
data
a data frame in which to evaluate the variables defined in formula(object).
groups
a data frame with the grouping factors corresponding to the glme model associated with object as columns, sorted from innermost to outermost grouping level.
conLin
an optional condensed linear model object, consisting of a list with components "Xy", corresponding to a regression matrix ( X) combined with a response vector ( y), and "logLik", corresponding to the log-likelihood of the underlying glme model. Defaults to attr(object, "conLin").
control
an optional list with control parameters for the initialization and optimization algorithms used in glme. Defaults to list(niterEM=20, gradHess=TRUE), implying that 20 EM iterations are to be used in the derivation of initial estimates for the coefficients of the reStruct component of object and, if possible, numerical gradient vectors and Hessian matrices for the log-likelihood function are to be used in the optimization algorithm.

VALUE:

an glmeStruct object similar to object, but with initialized model components.
