LASSOLKTData

Description

Forward and backwards stepwise search for a set of features and components

with tracking of nonlinear parameters.

Usage

LASSOLKTData(
  data,
  gridpars,
  allcomponents,
  allfeatures,
  preset = NA,
  presetint = T,
  specialcomponents = c(),
  specialfeatures = c(),
  specialpars = c(),
  removefeat = c(),
  removecomp = c()
)

Arguments

data	is a dataset with Anon.Student.Id and CF..ansbin.
gridpars	a vector of parameters to create each feature at
allcomponents	is search space for LKT components
allfeatures	is search space for LKT features
preset	One of "static","AFM","PFA","advanced","AFMLLTM","PFALLTM","advancedLLTM"
presetint	should the intercepts be included for preset components
specialcomponents	add special components (not crossed with features, only paired with special features 1 for 1)
specialfeatures	features for each special component (not crossed during search)
specialpars	parameters for the special features (if needed)
removefeat	Character Vector | Excludes specified features from the test list.
removecomp	Character Vector | Excludes specified components from the test list.

Value

data which is the same frame with the added spacing relevant columns.

list of values "tracetable" and "currentfit"
