Generate a random probability based on features of the simulation

Usage

cfg_beta_prob_rng(probability_fn = ~0.8, kappa_fn = ~0.1)

Arguments

probability_fn

a function which gives the time-varying mean of a beta distribution, The function will be called minimally with .x or `t“ which will be the time as a time period. Other variables may be present.

kappa_fn

a function which gives the time-varying dispersion of a beta distribution. The function will be called with minimally .x or t which will be the time period and .y or mean will be the mean. Other variables may be present.

Value

a time dependent function that inputs a time (as a time_period) and returns an probability for each day defined by the probability_fn and kappa_fn
