a response vector. Should be binary.
a vector identifying individuals or covariate strata
a vector with observation weights.
a model matrix; required.
a logical value or a character string; whether and how
a dispersion parameter should be estimated. For details see
the random effects design matrix.
dimension of random effects. Typically $d=1$ for random intercepts only, $d>1$ for models with random intercepts.
an optional numerical vector of starting values for the coefficients.
an optional model offset. Currently only supported for models without random effects.
an optional matrix of strarting values for the (co-)variance parameters.
an optional list of vectors with starting values for the random effects.
a character string, either "PQL" or "MQL", specifies the type of the quasilikelihood approximation.
a character string; either "ML" or "REML", specifies which estimator is to be used/approximated.
a list of parameters for the fitting process.
A list with components describing the fitted model.
