In EpiNow2: Estimate and Forecast Real-Time Infection Dynamics

Pack a dist_spec into stan-side init-prior fields

Description

Converts a ⁠<dist_spec>⁠ into the integer/vector representation consumed by the init-prior loop in inst/stan/estimate_infections.stan (data items init_dists, init_dist_params, init_lower, init_upper).

Usage

pack_init_prior(dist, lower_bound = 0)

Arguments

dist	A ⁠<dist_spec>⁠ (LogNormal, Gamma, or Normal).
lower_bound	Numeric, lower bound on the parameter's support.

Value

A list with elements dist_type (integer code: 0 = lognormal, 1 = gamma, 2 = normal), params (numeric, the distribution parameters), lower and upper (numeric scalars).
