A tool for projecting age patterns based on a standard age schedule and assumptions about relative risks using linear splines: TOPALS

Using a multistate model such as MicMac1 for making scenarios requires that assumptions need to be specified on the future values of many parameters, viz. transition rates distinguished by age, sex, forecast year and covariates like level of educational attainment. Particularly the distinction by age implies that many parameter values need to be specified. One solution is to specify model curves describing the age patterns and specify assumptions on the future values of th
