plotRes {countHMM}

Quantile-quantile and autocorrelation function plots of the pseudo-residuals.

Description

Plots quantile-quantile and autocorrelation function plots of the midpoints of the pseudo residual segments. For details, see Zucchini et al. (2016).

Usage

plotRes(mod)

Arguments

mod

An object of type countHMM (as returned by the function fitMod).

Value

A plot with two windows, the first of which displays the quantile-quantile function and the second of which displays the autocorrelation function of the pseudo-residuals.
