HH.regsubsets {HH}

Display tabular results for Best Subsets Regression.

Description

Print a tabular display of the results of Best Subsets Regression. This is an alternate display for the object from the regsubsets function. This function is based on regsubsets. The functions described here are designed for the HH package in R and use the leaps package in R. The leaps package is not in S-Plus, hence these functions do not work in the HH package for S-Plus.

Usage

`summaryHH`(object, ...)

## S3 method for class 'regsubsets'
summaryHH(object,
           names = abbreviate(dimnames(incidence)[[2]], minlength = abbrev),
           abbrev = 1, min.size = 1, max.size = dim(sumry$which)[2],
           statistic = c("bic", "cp", "adjr2", "rsq", "rss", "stderr"),
           las = par("las"),
           cex.subsets = 1, ..., main=statistic)

## S3 method for class 'summaryHH.regsubsets'
plot(x, ...,
           statistic="adjr2", legend=FALSE,
           col="darkgray", cex=1, pch=16,
           col.text="black", cex.text=1, col.abline="darkgray")

Arguments

object

An object of class "regsubsets".

x

An object of class "summaryHH.regsubsets".

statistic

Name of statistic to be plotted for each model.

...

Other arguments to be passed down to subsets.regsubsets and plot.

names

Abbreviations of variable names.

abbrev

minimum number of letters in each abbreviation.

min.size

minimum size subset to plot; default is 1.

max.size

maximum size subset to plot; default is number of predictors.

legend

logical variable, TRUE if the legend should be printed. If the legend is printed, the execution halts until the user clicks an empty space in the graph where the legend should be placed.

las

Orientation for model names on graph.

cex.subsets

can be used to change the relative size of the characters used to plot the regression subsets; default is 1.

main

"main" title for graph.

col, cex, pch

par values for dot locating statistic.

col.text, cex.text

par values for abbreviations of models on plot.

col.abline

par parameters for abline when the statistic is cp.

Value

summaryHH produces a table of models, with p, rsq, rss, adjr2, cp, bic, stderr for each. plot.summaryHH.regsubsets plots the specified statistic from the summary. All the others are support functions.
