More Commentary: Jerry Pournelle

Jerry Pournelle writes at Chaos Manor

I had refrained from commenting on the "hockey stick" because I couldn’t understand how it was derived. I’ve done statistical analysis and prediction from uncertainty much of my life. My first job in aerospace was as part of the Human Factors and Reliability Group at Boeing, where we were expected to deal with such matters as predicting component failures, and deriving maintenance schedules (replace it before it fails, but not so long before it fails that the costs including the cost of the maintenance crew and the costs of taking the airplane out of service are prohibitive) and other such matters. I used to live with Incomplete Gamma Functions and other complex integrals; and I could not for the life of me understand how Mann derived his famous curve. Now I know: he hasn’t told anyone. He says that telling people how he generated it would be tantamount to giving in to his critics. More on this after my walk, but the one thing we may conclude for sure is that this is not science

    Did Jerry ever expand on his remarks as he said he would? I couldn’t find it. Would ask him directly, but he dislikes me.
