Applying a Model Quick Start

Congratulations! You have collected calibration data and gone through the exercise of building a model that meets your objectives. Now, you want to apply one of the stiffest tests - applying your model to new data. If you have just completed the model building process, all that needs to be done is to load some new data as validation data. Another scenario is that you have a model that has been built awhile ago, and you wish to apply it to some new data.

In this example, there are three variables in the workspace

• mymodel - a PLS model that has been built on spectral data to predict a concentration
• spec2 - a new set of spectral data to be used to validate the model
• conc - concentration data for the validation spectra

The concentration data contains values for five separate components. The model mymodel predicts only one of these concentration values.
