Modeling Function Overview

Modeling Function Overview

High-Level Modeling Functions The following output a model structure (or similar) and are generally considered "high-level" modeling functions designed for relatively simple use by less-experienced users as well as expert users.

caltransfer - Create or apply calibration and instrument transfer models.

cluster - KNN and K-means cluster analysis with dendrograms.

cls - Classical Least Squares regression for multivariate Y.

corrspec - Resolves correlation spectroscopy maps.

frpcr - Full-ratio PCR calibration and prediction.

knn - K-nearest neighbor classifier.

lwr - Locally weighted regression for univariate Y.

mcr - Multivariate curve resolution with constraints.

mlr - Multiple Linear Regression for multivariate Y.

modelselector - Create or apply a model selector model.

evolvfa - Evolving factor analysis (forward and reverse).

ewfa - Evolving window factor analysis.

glsw - Generalized least-squares weighting/preprocessing.

gram - Generalized rank annihilation method.

lwrpred - Engine for locally weighted regression models.
