Risk in Modeling Check List

Good short piece on bias and Simpson's Paradox in DSC, by William Vorhies  In particular dealing with real time data.  Relatively non technical, beginners should be able to check off each of these risks before proceeding to process conclusions.   This post describes Simpson's Paradox well, I found it to be rare, but did once discover it in a particularly harmful case.   Again, I repeat, visualize your data first.  Make sure you consider the biases mentioned,  which can often be hidden.   That is a bias in itself.
