av_long_infected function

Average longevity: estimate for infected hosts

Calculates expected longevity of infected hosts due to background mortality and mortality due to infection

av_long_infected(a1, b1, a2, b2, d1 = "", d2 = "")

Arguments

• a1, b1: numeric: location & scale parameters for background mortality, respectively
• a2, b2: numeric: location & scale parameters for mortality due to infection, respectively
• d1, d2: character: probability distributions to describe background mortality and mortality due to infection, respectively

Returns

a vector

Details

The expected average longevity is calculated as the integral from zero to infinity for the product of the cumulative survival functions for background mortality and mortality due to infection, given values of a1, b1, d1, a2, b2, d2

Examples

av_long_infected(
    a1 = 3.0, b1 = 0.6, d1 = "Weibull",
    a2 = 2.5, b2 = 0.5, d2 = "Frechet") # 12.156
