Validate that the pmf vector being passed to stan is a valid probability mass function. It must sum to 1 and have all non-negative entries.

Usage

validate_pmf(
  pmf,
  calibration_time,
  count_data,
  tolerance = 1e-06,
  arg = "x",
  call = rlang::caller_env()
)

pmf: simplex vector describing a probabilty of an event ocurring on each day
calibration_time: integer indicating the calibration time
count_data: tibble containing the input count data ready to be passed to stan
tolerance: numeric indicating the allowable difference between the sum of the pmf and 1, default is 1e-6
arg: name of the argument supplying the object
call: The calling environment to be reflected in the error message
