This function returns the design matrix used for computation of the Bayes factor
for the numerator of a
BFBayesFactor object. There must not be more
than one numerator in the
## S4 method for signature 'BFBayesFactor' model.matrix(object, ...) ## S4 method for signature 'BFBayesFactorTop' model.matrix(object, ...)
a BayesFactor object with a single numerator
arguments passed to and from related methods
Returns the design matrix for the corresponding model. The 'gMap' attribute of the returned matrix contains the mapping from columns of the design matrix to g parameters
