What is the difference between a miss and a false alarm, then?
My definitions come from a Master's thesis done at Georgia Tech by Dr. Fred
Creamer.
I don't much care what words we use, but it is best if we can agree on definitions
before we try evaluating forecasts en masse.
Would anyone care to write definitions and give words to the following occasions:

1) An earthquake occurs but was not forecast.
2) A forecast was made but no corresponding earthquake occurred
3) A forecast was made and an earthquake completely matching the forecast
occurred, but the odds of random success were greater than 1 in 3 (or whatever
odds you chose for a successful prediction which would most likely have
occurred no matter whether the predictive method had any validity or not.
4) A forecast was made and an earthquake occurred which partially matched
the forecast parameters and the odds of occurrence were less than 1 in XX
i.e. a forecast which beat the odds of success considerably but was not
an exact match with the event.
5) A forecast completely describes a subsequent earthquake in all particulars
and the odds of random success are less than 1 in XX

Any other potential possibilities you can think of. We need words to these
whatever those words are, so we can describe these occasions when words
are necessary that we can all understand when we use them.
