find_mortality(annual.rate = 0.02)

Arguments

annual.rate

Double. Target annual mortality rate (in

Daily mortality probability.

Estimate daily p(dead) to match a target annual mortality rate

If the daily probability of a mortality event occurring is p, then the daily probability of survival is (1-p). The probability of survival over a year is then given by (1-p)^365. Therefore the probability of a mortality event occurring at least once during the year (annual mortality rate) is p_year = 1-((1-p)^365). It follows that p_day = 1-((1-p_year)^(1/365))
