Introduction

Simulation studies can be very useful when trying to understand the efficacy and nuances of different approaches to statistical modeling. This is because, in order to generate the data to analyze in the first place, the true model must be known. This appendix presents two simulation studies that provide insight on how PLS is likely to work in practice. Bear in mind, though, that any true ...
