In cancerpolicy/bcimodel: Model the impact of early detection and treatment interventions for breast cancer

Description

Takes in stats on cancer stage, subgroup (e.g. tumor type) and survival and compiles into a data frame of class 'naturalhist'. Note that this function could be modified to allow for more complex situations. Right now it presumes that mortality rates vary by stage only, and that stage and subgroup are uncorrelated.

Usage

compile_naturalhist(prop_adv, mortrates, subgroup_probs)

Arguments

prop_adv	Advanced Proportion of cancers presenting as Advanced stage
mortrates	Named vector of cancer mortality rates by stage, e.g. c(Early=.05, Advanced=0.21)
subgroup_probs	Named vector of subgroup probabilities that occur within stage groups, e.g. c('ER+'=0.5, 'ER-'=0.5)

Value

Data frame of class 'naturalhist' with columns stage, subgroup, mortrate and prop

Examples

compile_naturalhist(prop_adv=0.85, mortrates=c(Early=0.05, Advanced=0.21), 
                   subgroup_probs=c(`ER+`=0.5, `ER-`=0.5))
