print.MD: Print Best MD Follow-Up Experiments

Description

Printing method for lists of class MD. Displays the best MD criterion set of runs and their MD for follow-up experiments.

Usage

"print"(x, X = FALSE, resp = FALSE, Xcand = TRUE, models = TRUE, nMod = x$nMod, digits = 3, verbose=FALSE, ...)

Arguments

x

list of class MD. Output list of the MD function.

X

logical. If TRUE, the initial design matrix is printed.

resp

logical If TRUE, the response vector of initial design is printed.

Xcand

logical. Prints the candidate runs if TRUE.

models

logical. Competing models are printed if TRUE.

nMod

integer. Top models to print.

digits

integer. Significant digits to use in the print out.

verbose

logical. If TRUE, the unclass-ed x is displayed.

...

additional arguments passed to print generic function.

Value

The function is mainly called for its side effects. Prints out the selected components of the class MD objects, output of the MD function. For example the marginal factors and models posterior probabilities and the top MD follow-up experiments with their corresponding MD statistic. It returns invisible list with the components:

calc

Numeric vector with basic calculation information.

models

Data frame with the competing models posterior probabilities.

follow-up

Data frame with the runs for follow-up experiments and their corresponding MD statistic.
