“Lucky d20” (by Tamino, with my reblogging comments)

Careful consideration to really basic things like this is, for me, incredibly refreshing, and helps with the self-discipline needed to deal with real-world problems, those often being messy and having distracting entanglements. A couple of thoughts: I think the mechanism … Continue reading

Ah, Hypergeometric!

(“Ah, Hypergeometric!” To be said with the same resignation and acceptance as in “I’ll burn my books–Ah, Mephistopheles!” from Faust.)😉 Dr John Cook, eminent all ’round statistician (with a specialty in biostatistics) and statistical consultant, took up a comment I … Continue reading

All I do is complain, complain …

I was reviewing a presentation given as part of a short course in the machine learning genre today, and happened across the following two bullets, under the heading “Strictly Stationary Processes”: Predicting a time series is possible if and only … Continue reading

How nice it is that Nature and probability bend to developers whims!

As I have mentioned before, it’s so nice that Nature and probability bend to the whims of property developers and their Town Fathers, with the willing participation of the Federal Emergency Management Agency (FEMA). If you had property at risk … Continue reading

Incredible Rainfall In South Carolina, and Yes Climate Played A Role – Dan’s Wild Wild Science Journal – AGU Blogosphere

Make no mistake, this was a flood event unlike any other in South Carolina and while Hurricane Joaquin never hit the coast, it holds a smoking gun. This flood was the result of several factors, an … Source: Incredible Rainfall … Continue reading

Professor James Hansen responds and explains:

The recent paper by Hansen, Soto, and others has caused a stir, as I suspect it was intended to do so. I posted about this paper earlier. Now Professor Hansen has responded to the critics of his team’s work and … Continue reading
