Chapter 14
... When one variable changes by 1 unit, other correlated variables will change also (but we require it to be held constant in order to correctly interpret the coefficient). However, correlated independent variables do not affect a multiple regression equation’s ability to predict the dependent variable ...

limited dependent variable models ( censored and truncated )
... not available, the QLIM procedure offers a class of models that adjust for truncation. In case of censoring, the dependent variable is continuous only in a certain range and all values outside this range are reported as being on its boundary. For example, if it is not possible to observe negative va ...

Regression is used to describe a relationship between a quantitative response variable and one or more quantitative predictor variables. In this class we d ...
