Partial Factorials at Several Levels Calibration Designs

4 Partial Factorials at Several Levels Calibration Designs 

Two level designs are useful for exploratory purposes and can sometimes result in useful models, but in many areas of chemistry, such as calibration (see Chapter 5 for more details), it is desirable to have several levels, especially in the case of spectra of 

perform a calibration experiment, by producing a set of mixtures on a series of 

dten test dtis model on an independent set of mixtures called a test set  

finally, use the model on real data to produce predictions.
