VariablesSelection: Variables selection

In mridulaprasad/CorrDrugTumorMSI: A pipeline to combine drug distribution with tumor tissue-types in mass spectrometry imaging (MSI) data

Description

This function does variables selection using either spatial or non-spatial regression method. At the moment, function does variables selection for two class problem only where class of interest label as 2.

Usage

VariablesSelection(
  Inputdata,
  classids,
  method = "OLS",
  lagdist = 5,
  xycoord = 0
)

Arguments

Inputdata	ion intensity matrix
classids	class labels for variables selection
method	method used for variables selection, 'OLS', 'SL', 'SE'.
lagdist	the range of autocorrelation in spatial weight matrix for spatial methods
xcord, ycord	the xy co-ordinates of the MSI ion image
maskimage	exclude background pixels during variables selection

Value

regression coefficients and p-value for all variables
