Generalized linear model for mids object

Applies glm() to a multiply imputed data set

Usage

glm.mids(formula, family = gaussian, data, ...)

Arguments

formula: a formula expression as for other regression models, of the form response ~ predictors. See the documentation of lm and formula for details.
family: The family of the glm model
data: An object of type mids, which stands for 'multiply imputed data set', typically created by function mice().
...: Additional parameters passed to glm.

Value

An objects of class mira, which stands for 'multiply imputed repeated analysis'. This object contains data$m distinct glm.objects, plus some descriptive information.

Details

This function is included for backward compatibility with V1.0. The function is superseded by with.mids.
