Zero out random effects in a model object

Source: R/matlist.R

Sets all elements of the OMEGA or SIGMA matrix to zero

zero_re(.x, ...)

# S4 method for mrgmod
zero_re(.x, ...)

Arguments

.x

a model object
...

which matrix to zero out; pass omega to just zero out omega, sigma to just zero out sigma; passing nothing will zero out both

Value

An updated object.
