... Equations (lOa) and (b) are as before. Equation (lOc) exploits the information that we observe Y2 up to a positive factor of proportionality if Y21 is positive. 'These examples are not intended as a complete literature survey. Yet they illustrate that the basic statistical models for limited depende ...

... As people grow older, they gain height more slowly, so our fitted line is not good model at ages far removed from the data that produced it. Extrapolation Extrapolation is the use of a regression line for prediction far outside the range of values of the explanatory variable x that you used to obtai ...
