Internal functions for leaps(), subsets()
Description
These functions are used internally by regsubsets and leaps. They are wrappers for Fortran routines that construct and manipulate a QR decomposition.
Usage
leaps.setup(x,y,wt=rep(1,length(y)),force.in=NULL,force.out=NULL,intercept=TRUE,nvmax=8,nbest=1,warn.dep=TRUE)
leaps.seqrep(leaps.obj)
leaps.exhaustive(leaps.obj,really.big=FALSE)
leaps.backward(leaps.obj)
leaps.forward(leaps.obj)
Arguments
x |
A matrix of predictors |
y |
A response vector |
wt |
Optional weight vector |
intercept |
Add an intercept to the model |
force.in |
vector indicating variable that must be in the model |
force.out |
vector indicating variable that must not be in the model |
nbest |
Number of subsets of each size to report |
nvmax |
largest subset size to examine |
warn.dep |
warn if x is not of full rank |
leaps.obj |
An object of class leaps as produced by leaps.setup |
really.big |
required before R gets sent off on a long uninterruptible computation |
