summary.dcm: Summary Model Statistics

In EpiModel: Mathematical Modeling of Infectious Disease Dynamics

Summary Model Statistics

Description

Extracts and prints model statistics solved with dcm.

Usage

## S3 method for class 'dcm'
summary(object, at, run = 1, digits = 3, ...)

Arguments

object	An EpiModel object of class dcm.
at	Time step for model statistics. Must be one of the times the model was solved over, held in control$timesteps, which for a model with a non-integer dt or an explicit vector of times in nsteps need be neither integer nor evenly spaced.
run	Model run number, for dcm class models with multiple runs (sensitivity analyses).
digits	Number of significant digits to print.
...	Additional summary function arguments (not used).

Details

This function provides summary statistics for the main epidemiological outcomes (state and transition size and prevalence) from a dcm model. Time-specific summary measures are provided, so it is necessary to input a time of interest. For multiple-run models (sensitivity analyses), input a model run number. See examples below.

Examples

## Deterministic SIR model with varying act.rate
param <- param.dcm(inf.prob = 0.2, act.rate = 2:4, rec.rate = 1/3,
                   a.rate = 0.011, ds.rate = 0.01,
                   di.rate = 0.03, dr.rate = 0.01)
init <- init.dcm(s.num = 1000, i.num = 1, r.num = 0)
control <- control.dcm(type = "SIR", nsteps = 50)
mod <- dcm(param, init, control)
summary(mod, at = 25, run = 1)
summary(mod, at = 25, run = 3)
summary(mod, at = 26, run = 3)
