NPRED

Predictor Identifier: Nonparametric PREDiction (NPRED) Partial informational correlation (PIC) is used to identify the meaningful predictors to the response from a large set of potential predictors.

The initial version of NPRED is at Hydrology@UNSW. This is a new version of NPRED without calling Fortran codes.
