Lagrange multiplier (LM) test statistics are derived for testing a linear moving average model against an asymmetric moving average model and an LM type test for testing the same model against an additive smooth transition moving average model. The latter model is introduced in the paper. The small sample performance of the proposed tests is evaluated in a Monte Carlo study and compared to that of the Wald and likelihood ratio statistics. The size properties of the Lagrange multiplier test are better than those of other tests.
