Forecasting Age-Specific Brain Cancer Mortality Rates Using Functional Data Analysis Models

Table 5

Age- and gender-specific prediction of brain cancer mortality rates of young adults for the years 2009 and 2018. In the first table, prediction is made for all the patients under study. In the second table, perdition of mortality rates is made separately for middle age (20–64 years) subpopulation. Prediction of mortality rates show higher decreasing rate if analysis is done after clustering the data by age groups.
