Calculate a measure for dispersion

Description

The measure is calculated as the average of the squared Pearson residuals

Usage

dispersion(observed, fitted, variance)

Arguments

observed	the observed values
fitted	the fitted values
variance	the variance of the fitted values

Examples

library(INLA)
set.seed(20181202)
model <- inla(
  poisson ~ 1,
  family = "poisson",
  data = data.frame(
    poisson = rpois(20, lambda = 10),
    base = 1
  ),
  control.predictor = list(compute = TRUE)
)
dispersion(
  observed = get_observed(model),
  fitted = fitted(model),
  variance = fitted(model)
)
