In my last post I built a regression model with a single predictor variable. That variable represented the value of a single pixel from a 28×28 image of a hand written digit. In this post I will look at some model variations based on using a larger number of input variables.

Logistic Regression pt.1
In a recent post I created a table that contained two classes of data: images that represent either the handwritten digit ‘5’ or the digit ‘6’. In this post I’ll model the data using logistic regression. I will also take the opportunity to look at the role of training and test datasets, and to highlight the distinction between testing and validation.
The Power of Journals
If you have ever been to a JMP Discovery Summit or perhaps a JMP user group meeting you will no doubt have come across journal files. The first time you create one can be an unnerving experience since a new journal is simply a blank window. But that is their beauty: they are a blank canvass onto which you can save your JMP output. But more importantly they are a place to capture your thoughts.
