glmRob.cubif: Robust GLM CUBIF Fitter

Description

Robustly fit a generalized linear model using a conditionally unbiased bounded influence (“cubif”) estimator. This function is called by the high-level function glmRob when method = "cubif" (the default) is specified.

Usage

glmRob.cubif(x, y, intercept = FALSE, offset = 0,
        family = binomial(), null.dev = TRUE, control)

Arguments

x

a numeric model matrix.

y

either a numeric vector containing the response or, in the case of the binomial family, a two-column numeric matrix containing the number of successes and failures.

intercept

a logical value. If TRUE a column of ones is added to the design matrix.

offset

a numeric vector containing the offset.

family

a family object.

null.dev

a logical value. If TRUE the null deviance is computed.

control

a list of control parameters. See glmRob.cubif.control.

Value

See glmRob.object.
