How Hot Spot Analysis Should be Performed
Contained here is an example of best practice with regard to hot spotting. Readers
should recall the comments at the start of this toolkit that there is no "right" way
of identifying hot spots. There are so many different ways and circumstances to apply
hot spots that it is very difficult to present a definitive approach. Nonetheless,
the approach listed here contains the essential components but is sufficiently general
to accommodate specific applications.
The method for identifying hot spot has three distinct steps:
- How to measure the heat: Count or rates?
- Global tests
- Isolating hotspots
