[Geysers] [Fwd: Old Faithful regression formula]

[Lynn Stephens]

As Ralph noted, the prediction model is currently a simple prediction model 
rather than a regression model.  Because the staff has not been trained to 
time Old Faithful durations until the last drop of water, I  suspect it is 
no longer possible to generate an accurate regression model using recorded 
intervals and durations from the Old Faithful Visitor Center logbook.
