Adjust Poisson Distribution Parameters for Sensitivity Analyses

Expands (sd_mult > 1) or reduces (sd_mult < 1) the standard deviation of the Poisson distribution. Due to the parameterization of this distribution, adjusting the standard deviation necessarily changes the mean value.

sens_pois(lambda, sd_mult = 2)

Arguments

lambda

A non-negative numeric vector of means.

sd_mult

A non-negative multiplier on the standard deviation of the distribution.

Value

A named list of the adjusted distribution's parameters.
