For linear models, LRT and Z-tests are identical; t-tests are better because they take uncertainty ... WebbFor the multiple linear regression model, there are three different hypothesis tests for slopes that one could conduct. They are: Hypothesis test for testing that all of the slope parameters are 0. Hypothesis test for testing that a subset — more than one, but not all — of the slope parameters are 0.
