ABSTRACT
The two parts of this appendix can help understand the detailed calculations for Chapters 3, 6 and 7:
• The first part describes the Student distributions (centered and noncentered). They have also received the name of T-distributions. This distribution appears in many problems related to Normal models such as the salmon fish farm example (Chapter 3), the Thiof abundance ANCOVA of Chapter 6 and the regression approach in the stock/recruitment model in Chapter 7.
