Missing Data Scaling Functions

These functions can be used with data sets with missing values for mean centering (mdmncn.m), autoscaling (mdauto.m), scaling down (mdscale.m) and rescale up (mdrescal.m) data sets with missing values. Each of the functions uses a flag to indicate the location of missing data. They can be used with the PLS_Toolbox function for PCA with missing data (mdpca.m) prior to using it.

Requirements for running missing data scaling functions

  • MATLAB 5.0
  • No other toolboxes required
  • Must be a registered PLS_Toolbox user.
