summary.gSlc {gammSlice}

Summary of the generalized additive mixed model fit produced by gSlc

Description

A graphical table showing, for key model parameters, the Markov chain Monte Carlo samples, diagnostic plots and numerical summaries.

Usage

## S3 method for class 'gSlc'
summary(object,colour=TRUE,paletteNumber=1,...)

Arguments

object

A gSlc() fit object.

colour

Boolean flag:
TRUE = produce a colour graphical table,
FALSE = produce a black and white graphical table .

paletteNumber

If colour = TRUE then there there are two possible colour palettes. These are determined by whether paletteNumber is set to 1 or 2. The default is paletteNumber=1.

...

place-holder for additional arguments.

Details

The columns of the graphical table are:

1. parameter name,
2. trace plot of the Markov chain Monte Carlo sample,
3. plot of Markov chain Monte Carlo sample against its lag 1 sample,
4. sample autocorrelation function,
5. kernel density estimate of the posterior density function,
6. posterior mean and 95% credible interval.
