In this article, a method for the local analysis of the map-to-model fit is presented. The time delay effect reflects the policy factors of the epidemic situation and the actual treatment situation, so that the model fits the reality, has higher fitting accuracy, and reduces the uncertainty of model analysis to a certain extent. *e principal component analysis method is used to simplify many related factors into a few uncorrelated factors to eliminate the multicollinearity caused by too many dependent variables on this basis, the principal component regression model is constructed, and the determination coefficient is used to test the model fitting. The model fit was evaluated using the Hosmer and Lemeshow test. The major techniques elaborated in the model fitting for ordinal regression were stating which independent variables are most likely to be kept in the model and selecting the link function such as, (logit link, complementary log-log link, negative log-log link and probit link) which verified the model suitability. Optimal models were selected based on a combination of model fit (BIC), parsimony, and clinical plausibility. The sizes and mean residence times of labile, intermediate, and stable SOC pools were estimated by fractionation and model fitting to CO2 release during long-term incubation. CFA suggested the model fit the data well (ꭓ2=679. That same model fit the behavioral data well. Structured equation modeling has been was used to check the model fit of the proposed model, and path analysis revealed the correlations between the endogenous and exogenous variables of the study. We further develop Δ DIC as well as Δ LPML to determine the importance and contribution of the longitudinal data to the model fit of the T P and T D data.
