In ERSA: Exploratory Regression 'Shiny' App

Re-order model terms

Description

Re-order model terms

Usage

pvalOrder(m, d = NULL, refit = TRUE)

bselOrder(m, d = NULL, refit = TRUE, maxNPred = NULL)

fselOrder(m, d = NULL, refit = TRUE, maxNPred = NULL)

revPredOrder(m, d = NULL, refit = TRUE)

randomPredOrder(m, d = NULL, refit = TRUE)

regsubsetsOrder(m, d = NULL, refit = TRUE, collapse = TRUE)

Arguments

m	an lm objecct
d	the data frame. If NULL, attempts to extract from m.
refit	TRUE or FALSE
maxNPred	maximum number of predictors to use, defaults to all.
collapse	TRUE or FALSE

Value

a vector of terms in order last to first, or an lm if refit=TRUE. regsubsetsOrder returns a list of predictor vectors, or a list of fits

Functions

• pvalOrder(): Arranges model terms in order of increasing p-value

• bselOrder(): Arranges model terms using backwards selection

• fselOrder(): Forwards selection

• revPredOrder(): Reverses order of terms in a fit

• randomPredOrder(): Reorders terms in a fit randomly

• regsubsetsOrder(): Best subsets regression.

Examples

bselOrder(lm(mpg~wt+hp+disp, data=mtcars))
fselOrder(lm(mpg~wt+hp+disp, data=mtcars))
revPredOrder(lm(mpg~wt+hp+disp, data=mtcars))
randomPredOrder(lm(mpg~wt+hp+disp, data=mtcars))
regsubsetsOrder(lm(mpg~wt+hp+disp, data=mtcars))
