Objective: To solve the problem of parameter estimate in the regression analysis of non-random sample.Methods: Calculating residuals according to the regression function based on original data. Modifying residuals andcorrecting them with mean. Adding mean-corrected residuals on original response and bootstrapping them to get 1000samples. Fitting regression functions of 1000 resampling samples and calculating the 2.5
th
percentile and 97.5
th
percen-tile of corresponding coefficient. Results: The interval estimates deriving from boostrap method had more statistical
