In reply to Jon Dickens.

Hi, Jon. Thanks for writing. I'm not sure why you think there are two different data sets. My previous article has only one data set from which two different models are created. What you might have mistaken as a second "data set" is actually the sequence of 43 predicted values from the expert model, but those predictions are for the same set of 43 observations as the logistic model. Sorry if that was not clear.
