Statistical Models

Before we get into details regarding a few statistical tests, it might be important to discuss a few key concepts common across statistical models.

Some models might be quite good at capturing the truth of the process, while others might not be so good at it. The degree to which a model reflects the data used for analysis is the fit of the model. As I discussed in other posts, the fit is not everything, and the model should be generalizable. But I am getting ahead of myself...Let's go back to the fit.
