drop1.mm_lmm() refits reduced fixed-effect models and compares them to the
original fit. It is conservative: random-effect terms are preserved exactly,
and the reduced formulas are reported in the result table.
Usage
# S3 method for class 'mm_lmm'
drop1(
object,
scope = NULL,
test = c("none", "Chisq"),
refit_for_comparison = c("auto", "error", "ml"),
...
)
Arguments
- object
A fitted mm_lmm.
- scope
Optional character vector of fixed-effect terms to drop.
- test
Comparison test label. "Chisq" reports asymptotic LRT rows;
"none" reports information criteria only.
- refit_for_comparison
How to handle REML fits.
- ...
Reserved for future methods.
Value
An mm_drop1 object.
