When the default arguments are used, this returns a pmf corresponding to the incubation period for COVID after Omicron used in Park et al 2023. These estimates are from early Omicron.

Usage

make_incubation_period_pmf(
  backward_scale = 3.6,
  backward_shape = 1.5,
  r = 0.15
)

Arguments

backward_scale

numeric indicating the scale parameter for the Weibull used in producing the incubation period distribution. default is 3.60 for COVID

backward_shape

numeric indicating the shape parameter for the Weibull used in producing the incubation period distribution, default is 1.50 for COVID

r

numeric indicating the exponential rate used in producing the correction on the incubaion period distribution, default is 0.15 for COVID

Value

pmf of incubation period
