Just a “heads-up.”

I’ve been editing a two-part series Nina Zumel is writing on some of the pitfalls of improperly applied principal components analysis/regression and how to avoid them (we are using the plural spelling as used in following Everitt *The Cambridge Dictionary of Statistics*). The series is looking absolutely fantastic and I think it will really help people understand, properly use, and even teach the concepts.

The series includes fully worked graphical examples in R and is why we added the `ScatterHistN`

plot to WVPlots (plot shown below, explained in the upcoming series).

Frankly the material would have worked great as an additional chapter for Practical Data Science with R (but instead everybody is going to get it for free).

Please watch here for the series.
