Linear Regression is a way of simplifying a group of data into a single equation. Introduction. Cartilage T1rho values correlated positively with age for all cartilage regions tested (p<0.001). This book is a complete introduction to this statistical method. It is obvious that simple linear model is just specific case of multiple one with k=2 (p=1) Non-linear model y = A(1-e-Bx), where A, B are parameters In further discussion we restrict ourselves to multiple linear regression analysis.
