summary.epinet: Summarize posterior samples from epinet object

In epinet: Epidemic/Network-Related Tools

Description

Prints summaries of posterior samples generated by the epinet inference routine.

Usage

	## S3 method for class 'epinet'
summary(object, ...)
	

Arguments

object	an object of class epinet, produced from the epinet inference function.
...	other arguments to be passed to the summary routine.

Details

Prints summaries of the epidemic and network parameters of an epinet inference object. Epidemic parameters are beta, thetae, ke, thetai, and ki. Network parameters are specified in the model formula, and may include an intercept term.

Value

Strictly invoked for side effect.

Examples

# Simulate an epidemic through a network of 30
set.seed(3)
N <- 30
# Build dyadic covariate matrix (X)
# Have a single covariate for overall edge density; this is the Erdos-Renyi model
nodecov <- matrix(1:N, nrow = N)
dcm <- BuildX(nodecov)
# Simulate network and then simulate epidemic over network
examplenet <- SimulateDyadicLinearERGM(N, dyadiccovmat = dcm, eta = -1.8)
exampleepidemic <- SEIR.simulator(examplenet, N = 30, 
    beta = 0.3, ki = 2, thetai = 5, latencydist = "gamma")
# Set inputs for MCMC algorithm
mcmcinput <- MCMCcontrol(nsamp = 5000, thinning = 10, etapropsd = 0.2) 
priorcontrol <- priorcontrol(bprior = c(0, 1), tiprior = c(1, 3), teprior = c(1, 3), 
    etaprior = c(0, 10), kiprior = c(2, 8), keprior = c(2, 8), priordists = "uniform")
# Run MCMC algorithm on this epidemic
# Note: Not enough data or iterations for any real inference
examplemcmc <- epinet( ~ 1, exampleepidemic, dcm, mcmcinput, priorcontrol)
