Applicability of Simple Linear Regression Method on Water Absorption Rate Forecasting of PMMA and Its Composites

Abstract

On the basis of researching the steps of single linear regression forecasting method, taking water absorption rate forecasting of PMMA/MMT nanocomposites in H2SO4 solution, NaOH solution and H2O as examples, the applicability of single linear regression method on water absorption rate forecasting of PMMA and its composites was studied. The results show that the maximum water absorption rate relative error of forecasting results of composites in three kinds of medium is 7.02%, which is allowable for industrial application, and single linear regression method can be used in water absorption rate forecasting of PMMA and its composites.
