Calculates the probability of quitting required to balance the population
stocks (Current, Former, Never) given the flows (Initiation, Relapse, Mortality).
Usage
quit_est(
trend_data,
survivorship_data,
mortality_data,
relapse_data,
initiation_data,
min_age = 11,
max_age = 89,
min_year = 2003,
max_year = 2018
)
Arguments
- trend_data
Output of trend_fit().
- survivorship_data
Output of prep_surv().
- mortality_data
Output of smoke_surv().
- relapse_data
Output of prep_relapse() (aggregated version).
- initiation_data
Output of init_adj().
- min_age, max_age, min_year, max_year
Integers.
Details
Solves the equation:
N(t+1) = N(t) * Survival * (1 - Quit) + (Former * Relapse) + (Never * Init)
Rearranged to solve for Quit.
