【Abstract】 Based on Multi-dimensional return mathematical model,we have given out some application examples of one dimension and multi-dimension.At the same time,we obtained the normal equation coefficient matrix,the inverse matrix and regression coefficient with corresponding function in MATLAB quickly.We proposed the multi-dimensional return model examination process simultaneously,which includes R-examination,F-text and T-test as well as concrete application method.At last,we proposed the multi-dimension return method application step.更多还原
