- OrdinalGEE.compare_score_test(submodel)¶
Perform a score test for the given submodel against this model.
- Parameters:
- submodel
GEEResults
instance
A fitted GEE model that is a submodel of this model.
- submodel
- Returns:
Notes
The score test can be performed without calling ‘fit’ on the larger model. The provided submodel must be obtained from a fitted GEE.
This method performs the same score test as can be obtained by fitting the GEE with a linear constraint and calling score_test on the results.
