CRA (Critical Regression Analysis)

Critical regression analysis. Based on generalization analysis, piecewise regression and generalized Chow test, the functional regression division (FRD) method, also known as critical regression analysis (CRA), is proposed to determine the optimal division point in several common nonlinear mutation models. The core is to calculate the minimum pooled residual root mean square of each critical regression model.
