MCMCpack (version 1.4-4)

topmodels: Shows an ordered list of the most frequently visited models sampled during quantile regression stochastic search variable selection (QR-SSVS).

Description

Given output from quantile regression stochastic search variable selection, this function returns a table of the 'best' models together with their associated empirical posterior probability.

Usage

topmodels(qrssvs, nmodels = 5, abbreviate = FALSE, minlength = 3)

Arguments

qrssvs

An object of class qrssvs. Typically this will be the gamma component of the list returned by SSVSquantreg.

nmodels

The number of models to tabulate.

abbreviate

Logical: should the names of the predictors be abbreviated?

minlength

If abbreviate is set to TRUE, the minimum length of the abbreviations.

Value

A table with the models and their associated posterior probability. The models are arranged in descending order of probability.
