In many regression applications, the predictors naturally fall into two categories: "predictors of primary interest" and "predictors of secondary interest". It is often desirable to have a dimension reduction method that focuses on the predictors of primary interest while controlling the effect of the predictors of secondary interest. To achieve this goal, we propose a partial dimension reduction method via projective resampling of a composite vector containing the response variable and the predictors of secondary interest. The proposed method is general in the sense that the predictors of secondary interest can be quantitative, categorical or a combination of both. A special application of the proposed method for estimation in partially linear models is emphasized. The performance of the proposed method is studied through simulations, and its usefulness is demonstrated by applications to two real datasets.
