ABSTRACT
Well, that’s all there is to it! We have explored the 4 methods of quantitative analysis that are in widespread use, CLS, ILS, PeR, and PLS. We have considered the strengths and weakness of each method. The most important lesson we have (hopefully) learned is that no single method is right for all situations. Depending upon the nature of the application and the data we have to work with, any one of the 4 techniques might outperform the others. Fortunately, with the availablity of various software packages together with inexpensive computers on which to run them, it is a relatively easy matter to try them all on our data so that we may choose the method which best meets each situation.
