check: Check goodness of fit for 'mobility.model' class

In COVID-19-Mobility-Data-Network/mobility: Tools for Analyzing Human Mobility Data

Description

This function takes a fitted mobility mobility.model object and calculates goodness of fit metrics. If the Deviance Information Criterin (DIC) was calculated in the supplied model object, it is included in output. When plots = TRUE, two plots are shown containing the posterior distribution of trip counts compared to observed data and a Normal Q-Q plot showing the quantiles of model residuals against those expected from a Normal distribution.

Usage

check(object, plots, ...)

Arguments

object	a mobility.model object produced by the mobility function
plots	logical indicating whether to plot the Posterior Predictive Check and Normal Q-Q Plot (default = TRUE)
...	further arguments passed to or from other methods

Details

Goodness of fit metrics include:

DIC

Deviance Information Criterion

RMSE

Root Mean Squared Error

MAPE

Mean Absolute Percent Error

R2

R-squared

Value

a list of goodness of fit measures
