Conditional Logistic Regression - NCSS
The deviance in Cox regression is analogous to the residual sum of squares in multiple regression. In fact, when the deviance is calculated in multiple regression, it is equal to the sum of the squared residuals. The change in deviance, ∆D, due to excluding (or including) one or more variables is used in Cox regression just

Chapter 18 Estimating the Hazard Ratio What is the hazard?
www.u.arizona.eduCox regression Cox regression is a regression model that enables us to estimate the hazard ratio (hazard rate ratio) — a measure of effect which may be computed whenever the time at risk is known. The model is named after the statistician who wrote the regression equation and proposed a method to solve it (to estimate the coefficients).

Logistic regression was proposed as an alter-native in the late 1960s and early 1970s (Cabrera, 1994), and it became routinely available in statistical packages in the early 1980s. Since that time, the use of logistic ...

Box-Cox Transformations
www.statvision.comThe Box-Cox Transformations procedure is designed to determine an optimal transformation for Y while fitting a linear regression model. It is useful when the variability of Y changes as a function of X. Often, an appropriate transformation of Y both stabilizes the variance and makes the deviations around the model more normally distributed.
