 Regression Analysis 

Simple regression 

With elections looming this year, one would be wise to include the most electable candidate available (photo to the right).

From the kind folks at The Minitab Blog, here is an excellent series of pages on interpreting R-squared and assessing goodness of fit.

I am delighted that they included Apple Jacks, which were my favorite as a youngster.

Logistic regression
