Berkeley, Jessicafor her manifest love,her latent support,her outer energy,and her inner wish my college teachers would have taught many more things than the onesthey did.
2 Preferably, I would have liked to be taught more computational coursesand programming classes. They taught me the basics but they missed one keylesson that I learned years later with a blend of great disillusionment and enrichingexperience:the important Modeling should take place in the mind of the analyst,not in the computer. Computers and software are indispensable but they can tmake sense of data; only people who have developed the necessary data analysisskills can. Whether it is PLS path Modeling or any other type of Modeling ,always remember this little-big ModelContentsPreface.

10 So,how did you like the symposium? Tomas asked me. The week before we had hosted thePLS 05 International Symposium on PLS and Related Methods. It was my first academicconference ever and I had just been introduced to the PLS methods early that year. Ikind of liked it I responded. What was your favorite talk? , Tomas said. Well, I likedthis guy s presentation and also the case study in that woman s talk I answered vaguely. Iwas part of the staff and my role during the symposium was to be in charge of one of theconference halls.
