test_incidence_fit: Test homogeneous Poisson assumption of disease incidence.

Description

This function compares the actual variance of the yearly incidence rates with rates simulated from a Poisson process with overall rate equal to the overall mean rate.

Usage

test_incidence_fit(inc, N_sim = 1e+05)

Arguments

inc

Vector of absolute incidence values for each included year of the registry as generated by yearly_incidence.

N_sim

Number of simulations to perform.

Value

Vector of p-values for over- and under-dispersion based on the position of the observed sequence variance in the distribution.
