    Siri carefully read your article on horse racingsappears to me that this approach, taking real data and applying statistic thinking,should be very helpful for people as me, who wants to spread the message on statistics as a real life tool.regards,

    Great analysis, and a compelling illustration of the need to 'listen to the control chart'. (Ironically, Quality Digest, where the original article appeared, has an article with the same message…) But you didn't follow through to answer the original question: What is the probability of a horse beating Secretariat’s record? Given that the 3 races are not independent experiments, one cannot simply take the product of the 3 probabilities of beating Secretariat in each one. Some sort of Bayesian network analysis needed?

      Thanks for the comment, Chris.  Yes, I guess I did not answer that question – just what is the probabilty of a horse beating Secretariat's record in each individual race.  That was the stated purpose of their analysis – mine was a little different – to listen to the control chart.  But, I am not sure how I would proceed to come up with one probability.  I have not done anything with Bayesian network analysis.
