In order to evaluate the clinical study of the prescription efficacy of Kampo formula, blood pressure and serum cholesterol were used as subjects. Subjects whose test data was higher or lower than the standard value were included in the analysis. The data obtained before and after the treatment were analyzed for the average regression. The impact of this will cause changes in the inspection value, and the export of wrong analysis results will hinder the correct evaluation of the Chinese prescription. For this reason, the Akaike Information Criterion (AIC) analysis method was proposed. 1 Effect of mean regression: Patients with serum cholesterol values greater than a certain value were used as subjects. After taking Kampo prescriptions, they were evaluated for efficacy. Assume that the subject is ruled
