Error of Dummy Variable Treatment of Death Penalty in Regression Model —— From the Perspective of Execution and Evolution

Abstract

With the evolution of the empirical law methodology, a large number of statistical models have been applied in the field of law. When dealing with regression models, if the application of death penalty occurs, empirical law papers tend to deal with virtual variables, that is, to assign a value of 0 or 1. From the perspective of the evolution of execution, gun execution and injection are to abandon the cruel execution out of humanitarian care, rather than think that the standard above the death penalty is the equal evil, so it is not reasonable to treat the virtual variable of the death penalty. Through empirical research, it is found that whether the penalty amount is virtual variable treatment has a significant impact on the regression coefficient of the final regression equation, and the empirical research results are consistent with the prediction.
