Kaplan-Meier analysis

The blokes at Pythian are damn smart.
Paul Vallee mentioned the use of a statistical analysis of survival. Specifically Kaplan-Meier survival analysis.
After Paul explained how he was using it, I thought of other areas where you could use it. It comes down to how or what you class as being survival and death.

  1. Database performance. At what point does the performance hang (or die) and what is the mean time of survival. Survival could be a reasonable response time for a known query.
  2. Stock survival. The ASX whilst having large blue chip stocks continues a lot of speculative mining and biotech startups. It would be interesting to run some survival analysis over them.
This tool doesn't tell you what is required to survive and that would be heavily influenced by choice of the survival indications.

Anyway I have to go. Going to play computer games all afternoon. Should be good.

Have Fun
