Regression Analysis

Regression modeling is probably the most widely used (and misused) statistical tool in the analysis of data. Assume that we have two or more variables, that they are associated (correlated), and that the variable of interest is difficult to assess. However, the other variables are cheaper, easier or faster to obtain. Then, it is appropriate to use regression to find a model that expresses the variable of interest, as a function of all the others.
