The Study of Liver Surgery Patients’ Life Model Based on the Multiple Linear Regression Analysis Method

摘要

In this paper, multiple linear regression analysis method is used to solve the relationship, between a liver patient survival time after surgery and his several survival indexes. Through the model solution and the comparative analysis of the model, results show that in all possible combination of model variables, the model composed by the following four factors: blood coagulation value, prognostic index, the value of enzyme tests, liver function test values, has the highest coefficient of determination and the smallest residual error. So it is the best model.
