Global blinding, or Nature’s revenge against meteorologists who deny climate disruption

Posted on 6 April 2017 by ecoquant

Given climate disruption due to radiative forcing from excess atmospheric CO2, which is a premise of this blog, it is only reasonable to wonder about, speculate, hypothesize, and posit that eventually the amount of this forcing and the feedbacks in … Continue reading →

“Human activity has nothing big enough to affect Earth”

Posted on 14 March 2015 by ecoquant

“Human activity has nothing big enough to affect Earth.” That’s disingenuous and, usually, the speaker knows better but is trying to dissuade an audience from thinking human activity does. Or they parrot someone who is trying to do that. But … Continue reading →

Markov Chain Monte Carlo methods and logistic regression

Posted on 9 March 2015 by ecoquant

This post could also be subtitled “Residual deviance isn’t the whole story.” My favorite book on logistic regression is by Dr Joseph Hilbe, Logistic Regression Models, CRC Press, 2009, Chapman & Hill. It is a solidly frequentist text, but its … Continue reading →

Codium fragile, for Saturday, 17th January 2015

Posted on 17 January 2015 by ecoquant

With today’s post, I’m beginning a new tradition at 667 per cm, posting a potpourri of short observations collected during the week, not necessarily having dense citations to work which inspired them. (Although if interested, please do ask and I’ll … Continue reading →

‘We’re due for one; it’s time’

Posted on 8 September 2014 by ecoquant

The title is a paraphrase. This post is written with some irritation at a NOAA meteorologist, (presumably Dr) Glen Field who, on camera, flaunts his poor knowledge of probability and statistics, and misleads the public in doing so. See this … Continue reading →

“Without even thinking very hard …”: My favorite post from RealClimate

Posted on 17 February 2014 by ecoquant

Professor Ray Pierrehumbert’s “Open Letter to Steve Levitt” has to be my favorite post on RealClimate. Not only does it do “Consider a spherical cow” kinds of quick calculation, in a Socratic manner it exposes the manipulation which climate deniers or, if … Continue reading →

Nerds vs. Breaking Bad

Posted on 10 October 2013 by ecoquant

Very worthwhile to read Okazaki’s Nerds vs. Breaking Bad. I have just watched the first three episodes of this show and I have mixed feelings about it. I’m not giving it a review here but just want to make three … Continue reading →

“Double Plus Big Data”

Posted on 25 September 2013 by ecoquant

Big Data. All the rage. Why? Apart from distributed software folks strutting their stuff, something which is likely to be fleeting, especially when quantum computing comes around, what does it buy anyone? I can see four possibilities, which I consider … Continue reading →

My favorite definitions from Professor Andrew Gelman

Posted on 4 May 2013 by ecoquant

Professor Gelman has a nice list of statistical definitions, educational like nearly everything he does or writes: The Folk Theorem: When you have computational problems, often there’s a problem with your model. Second-Order Availability Bias: Generalizing from correlations you see … Continue reading →
