The renewal equation assumes no same-day transmission. This assumption
means that when working with a generation interval formatted as a PMF
we need to remove the element corresponding to day zero. This function
drops the element and renormalizes the remaining density to sum to one.
Usage
truncate_and_renormalize(pmf, tol = 1e-10)
Arguments
- pmf
A probability mass function formatted as a vector. Usually a
generation interval indexed from day 0.
- tol
The numerical tolerance applied to the sum-to-one check on the
renormalized PMF.
Value
A probability mass function with no density in the first bin.
