aStep2: Update Observation Set in Step 2

In forsearch: Diagnostic Analysis Using Forward Search Procedure for Various Models

Update Observation Set in Step 2

Description

Derives the set of observation numbers for forsearch in Step 2 for linear models

Usage

aStep2(yesfactor, form.A2, finalm, rimbs, onlyfactor = FALSE, dfa2, finalm.ls,
          ycol,mstart, rnk, b.d)

Arguments

yesfactor	True or False for presence of factors
form.A2	Formula for analysis of entire dataset
finalm	See VALUE above. finalm argument is the same but only for Step 1 values
rimbs	List, each element is a matrix of obs numbers and corresponding subset codes
onlyfactor	Logical. TRUE if there are no continuous independent variables in the model
dfa2	Data frame being analyzed by forward search. Presence of Observation column has no effect on output
finalm.ls	List showing finalm separated into factor subsets
ycol	Response column number, including 1 for Observation
mstart	Number of first subset to be defined in Step 2
rnk	Rank of X matrix. For factors, this is rank with factors removed.
b.d	Number at which to begin diagnostic listings

Details

Support function, usually not called independently

Value

Vector of integers corresponding to observation numbers
