lmeb-class: Relationship-based mixed-effects model fits

Description

A mixed-effects model fit by lmeb. This class extends class "merMod" class and includes one additional slot, relfac, which is a list of (left) Cholesky factors of the relationship matrices derived from "lmeb" objects.

Objects from the Class

Objects are created by calls to the lmeb function.

Slots

relfac:

A list of relationship matrix factors. All other slots are inherited from class "merMod".

udu:

A list of eigen decomposition elements. All other slots are inherited from class "merMod".

Extends

Class "merMod", directly.

Methods

fitted

signature(object = "lmeb"): actually a non-method in that fitted doesn't apply to such objects because of the pre-whitening.

ranef

signature(object = "lmeb"): back-transforms BLUPs and their conditional variances when models include the relationship between levels of random effects as returned for the object viewed as a "merMod)" object.

residuals

signature(object = "lmeb"): also a non-method for the same reason as fitted
