Abstract: We propose a projection-based test to check partially linear models. The proposed test gains dimension reduction and makes the proposed method act as if only one covariate exists in the presence of multiple dimensional regressors. The test is shown to be consistent and can detect the Pitman local alternative hypothetical models. We further derive asymptotic distributions of the proposed test under the null hypothesis, and local and global alternatives. Most importantly, its numerical performance is consistently and remarkably superior to its competitors. Real examples are presented for an illustration.
