that fits exactly to existing (DOE) data points. In Encore, the example of this is Kriging. However, a function that fits your data exactly may not be a good predictive model of your phenomenon. Such a transfer function may yield very poor predictions of data points that are between (amidst) your data, or...

* represented in std deviation units
* z-score of 0 is equal to the mean of the sample
* the area beneath the curve between two points gives the probability of randomly selecting a score between those two points

In practice, a certain segment of data will be labelled with these classifications. The machine learner's task is...

In addition to grouping data, we often graph them to better visualize any patterns in the data. Seeing data displayed graphically can significantly deepen our understanding of a data set and the situation it describes.
In many data sets, there are occasional values that fall far...
