Description

Backward covariate search

Usage

backwardSearch(
  covInfo,
  fitorig,
  fitupdated,
  pVal = 0.01,
  reFitCovars = FALSE,
  outputDir,
  restart = FALSE
)

Arguments

covInfo

a list containing information about each variable-covariate pair
fitorig

the original 'fit' object before forward search
fitupdated

the updatef 'fit' object, if any, after the forward search
pVal

p-value that should be used for selecting covariates in the forward search
reFitCovars

if the covariates should be added before performing backward search - useful for directly performing backward search without forward search; default is FALSE
outputDir

the name of the output directory that stores the covariate search result
restart

a boolean that controls if the search should be restarted; default is FALSE
