A nonautonomous SIR epidemic model with age structure is studied.
This paper is organized as follows: Section 2 introduces a non-autonomous SIR model with age structure.
In this paper, existence of positive period solution of a non-autonomous SIR epidemic model with age structure is studied.
Combining age with Site Index reduced the RMSE to 1.46 m while a model with age and mean REVI had an RMSE of 1.52 m (Table 3).
The final model with age, Site Index and mean REVI had an RMSE of 2.96 m and R2 of 0.936 (Table 4).
The striatal measure of DAT availability was analyzed in a multiple regression model with age, SPECT centre and smoking as predictor.
However gains obtained through adding REVI and Site Index to the base model with age did not result in model improvement at the Tairua site.
The results of the Ordered Logit model with age at arrival categorical dummies as well as with continuous age at arrival high-order polynomial are presented in Tables 5 and 6 for males and females, respectively.
The Cox proportional hazard regression model with "age groups" and "APACHE-II score" as covariates was used to evaluate the C and C' path, only for potential mediators having significant (P < 0.05) associations in both the A and B paths.
However, the addition of frailty and comorbidity provided a further significant risk reclassification in comparison to the clinical model with age (continuous net reclassification improvement, 0.40; 95% CI, 0.16-0.65; and integrated discrimination improvement, 0.04; 95% CI, 0.01-0.10).
