All functions

calc_allrmds(): Calculate restricted mean durations for each health state and all three models

calc_haz_psm(): Derive pre and post-progression hazards of death under PSM

calc_likes(): Calculate likelihoods for three three-state model structures

calc_rmd(): Calculate restricted mean durations

calc_surv_psmpps(): Derive PPS survival function under a PSM

check_consistent_pfs(): Check consistency of PFS definition Check that PFS is defined consistently with TTP and OS in a dataset. This convenience function compares pfs.durn with the lower of ttp.durn and os.durn, and checks that the event field pfs.flag is consistent with ttp.flag and os.flag (is 1 when either ttp.flag or os.flag is one).

compare_psm_likes(): Compare likelihoods of PSMs

constrain_survprob(): Constrain survival probabilities according to hazards in a lifetable Recalculated constrained survival probabilities (by week) as the lower of the original unadjusted survival probability and the survival implied by the given lifetable (assumed indexed as years).

create_dummydata(): Create dummy dataset for illustration

create_extrafields(): Create the additional time-to-event endpoints, adjusting for cutpoint

find_bestfit(): Find the "best" survival regression from a list of model fits

fit_ends_mods_par(): Fit multiple parametric survival regressions to the multiple required endpoints

fit_ends_mods_spl(): Fit multiple spline regressions to the multiple required endpoints

graph_psm_hazards(): Graph the PSM hazard functions

graph_psm_survs(): Graph the PSM survival functions

graph_survs(): Graph the observed and fitted state membership probabilities

prob_os_psm(): Calculate probability of being alive in a partitioned survival model

prob_os_stm_cf(): Calculate probability of being alive under the state transition clock forward model

prob_os_stm_cr(): Calculate probability of being alive under the state transition clock reset model

prob_pd_psm(): Calculate membership probability of progressed disease state in a partitioned survival model

prob_pd_stm_cf(): Calculate probability of having progressed disease under the state transition clock forward model

prob_pd_stm_cr(): Calculate probability of having progressed disease under the state transition clock reset model

prob_pf_psm(): Calculate probability of being progression free in partitioned survival model

prob_pf_stm(): Calculate probability of being progression free in either state transition model (clock forward or clock reset)

prob_pps_cf(): Calculate probability of post progression survival under the state transition clock forward model

prob_pps_cr(): Calculate probability of post progression survival under the state transition clock reset model

vlookup(): VLOOKUP function
