The hardest logarithm to compute

Suppose you want to compute the natural logarithms of every floating point number, correctly truncated to a floating point result. Here by floating point number we mean an IEEE standard 64-bit float, what C calls a double. Which logarithm is hardest to compute?
We’ll get to the hardest logarithm shortly, but we’ll first start with a warm up problem.

Though we have to draw some inferences to get there, it appears that most, quite possibly all terrestrial superstations have a higher profit margin than Netflix

Another data point in our long-running thread. On December 10th, 2018, Katz Broadcasting (owned by the E. W. Scripps Company) announced that they would relaunch Court TV as an over-the-air network following the acquisition of the intellectual property rights to the Court TV name and the pre-2008 Court TV original programming library from Turner Broadcasting System and Warner Bros. Entertainment.

De l’abus de notation dans les modèles de régression

De manière un peu rituelle, je commence toujours mon cours de régression en revenant sur un point important de la statistique : les abus de notation !  Car tout le monde utilise les mêmes lettres (surtout les grecques) pour désigner des objets de nature différente. Dans la majorité des livres, on pourra nous dire sur la même page que widehat{theta}=2.35 et que text{Var}(widehat{theta})=1.

He grins like a Cheshire cat; said of anyone who shows his teeth and gums in laughing

So you know the Cheshire cat, yeah?  Ever wonder what it’s point is?  Like, it turns up in a number of places, but does it foreshadow or emphasize plot turns?  Might it signify coming improvements or declines?
In my last post I confirmed that plot arcs from smoothed word sentiments seem to provide sensible representations of the plot progressions.

Just evaluating a polynomial: how hard could it be?

The previous post looked at an example of strange floating point behavior taking from book End of Error. This post looks at another example.
This example, by Siegfried Rump, asks us to evaluate
333.75 y6 + x2 (11 x2y2 – y6 – 121 y4 – 2) + 5.5 y8 + x/(2y)
at x = 77617 and y = 33096.
Here we evaluate Rump’s example in single, double, and quadruple precision.
