Check target size against number of reference times available and the number required

Usage

.check_against_requirements(
  n_ref_times,
  n_required,
  n_target,
  n_min_delay,
  n_min_retro_nowcasts,
  scale_factor,
  max_delay
)

Arguments

n_ref_times

Integer indicating the number of reference times available

n_required

Integer indicating the number need for both delay and uncertainty

n_target

Integer indicating the target number of reference times.

n_min_delay

Integer indicating the number needed for delay estimation.

n_min_retro_nowcasts

Integer indicating the number needed for uncertainty estimation.

scale_factor

Numeric value indicating the multiplicative factor on the maximum delay to be used for estimation of delay and uncertainty. Default is 3.

max_delay

Integer indicating the maximum delay to estimate, in units of the delay. The default is to use the whole reporting triangle, ncol(reporting_triangle) -1.

Value

n_used Integer indicating how many reference times will be used
