score_test
()[source]¶ Return the results of a score test for a linear constraint.
- Returns
- Adictionary
containing
the
p-value,the
test
statistic, and
the
degrees
of
freedom
for
the
score
test.

Notes
See also GEE.compare_score_test for an alternative way to perform a score test. GEEResults.score_test is more general, in that it supports testing arbitrary linear equality constraints. However GEE.compare_score_test might be easier to use when comparing two explicit models.
