make_ar_extrap_samps: Make AR samples for extrapolation past end point

In incidental: Implements Empirical Bayes Incidence Curves

Description

Make auto-regressive (AR) samples for extrapolation past end point to help with right-censoring problems.

Usage

make_ar_extrap_samps(
  reported,
  num_ar_steps = 10,
  num_ar_samps = 50,
  seed = 1,
  linear_tail = 14,
  extrapolation_prior_precision = 2
)

Arguments

reported	An integer vector of reported cases.
num_ar_steps	An integer number of AR steps after last observation.
num_ar_samps	An integer number of AR samples.
seed	Seed for RNG.
linear_tail	An integer number of days used to fit linear model on tail to be used as a mean for AR extrapolation.
extrapolation_prior_precision	A positive scalar for extrapolation slope shrinkage prior precision.

Value

A matrix of size (num_ar_samps x n + num_ar_steps)
