Printing Objective Posterior Probabilities from Bayesian Design

Description

Printing method for lists of class OBsProb. It prints the posterior probabilities of factors and models from the Objective Bayesian procedure.

Usage

    ## S3 method for class 'OBsProb'
print(x, X = TRUE, resp = TRUE, factors = TRUE, models = TRUE,
            nTop, digits = 3, plt = FALSE, verbose = FALSE, Sh= TRUE, CV=TRUE,...)

Arguments

`x`	list. Object of `OBsProb` class, output from the `OBsProb` function.
`X`	logical. If `TRUE`, the design matrix is printed.
`resp`	logical. If `TRUE`, the response vector is printed.
`factors`	logical. If `TRUE`, marginal posterior probabilities are printed .
`models`	logical. If `TRUE`, models posterior probabilities are printed.
`nTop`	integer. Number of the top ranked models to print.
`digits`	integer. Significant digits to use for printing.
`plt`	logical. If `TRUE`, factor marginal probabilities are plotted.
`verbose`	logical. If `TRUE`, the `unclass`-ed list `x` is displayed.
`Sh`	logical. If `TRUE`, the Shannon index is printed.
`CV`	logical. If `TRUE`, the coefficient of variation is printed.
`...`	additional arguments passed to `print` function.

Value

The function prints out marginal factors and models posterior probabilities. Returns invisible list with the components:

`calc`	numeric vector with general calculation information.
`probabilities`	Data frame with the marginal posterior factor probabilities.
`models`	Data frame with model posterior probabilities.
`Sh`	Normalized Shannon heterogeneity index on the posterior probabilities of models
`CV`	Coefficient of variation of factor posterior probabilities.
