NEW : SART : Statistical Analysis of Rates and Trends
This application allows for 1) descriptive analysis of frequencies (Crude Rates, Age-Standardized. Truncated Rates, Cumulative Risk) 2) Annual percent change of age-standardized rates 3) Standardized incidence or mortality ratio and 4) Projection of the number of incident cases.

RiskDiff : Analysis of the difference due to risk and demographic factors for incidence or mortality data.
This tool can be useful to study the differences in the incidence or mortality observed in two given situations (such as time points, geographical areas, or males versus females). The method performed splits the observed differences into three components: (1) the risk itself, (2) difference attributed to changes in the population size and (3) difference attributed to changes in population structure.

NEW : WAERS: Web Assisted Estimation of the Relative Survival.
Automatic calculation of Stratified Relative Survival (RS) can be performed. Relative survival (RS) can be interpreted as the proportion of patients alive after T years of follow-up in the hypothetical situation that cancer is the only possible cause of death.
