Predict Method for glmmPQL Fits

Description

Obtains predictions from a fitted generalized linear model with random effects.

Usage

## S3 method for class 'glmmPQL':
predict(object, newdata = NULL, type = c("l suign matrix be returned?

y

should the response be returned?

contrasts

a list of contrasts to be used for some or all of factor terms in the
formula. See the contrasts.arg of model.matrix.default.

...

additional arguments to lm.fit.



Details

If an intercept is present in the model, its coefficient is not penalized. (If you want to penalized an intercept, put in your own constant term and remove the intercept.)

Value

A list with components

coef matrix of coefficients, one row for each value of lambda. Note that these are not on the original scale and are for use by the coef method.
scales scalings used on the X matrix.
Inter was intercept included?
lambda vector of lambda values
ym mean of y
xm column means of x matrix
GCV vector of GCV values
kHKB HKB estimate of the ridge constant.
kLW L-W estimate of the ridge constant.
