Re: How good or bad are the pandemic warning models?

China’s aggressive measures have slowed the coronavirus. They may not work in other countries

"The question now is whether the world can take lessons from China’s apparent success" (so far)

Still, excellent news!

Re: Trump -- the last 100 days

No, I can see the confusion, but it means what it says. If I wanted to make up a story about Democrats, I would have.

Re: Trump -- the last 100 days

Strange timing, IMO. He might have done well in California on Super Tuesday. Why not wait and find out? Just had an idea for "Mike will get it done" Bloomberg. Take the next $100 million targeted for tv ad spending and, instead, fund a fast, stealth COVID-19 vaccine effort, in case the current vacci...

Re: Trump -- the last 100 days

So, this is obviously par for the course, but the president-princeling made an interesting observation about Democrats today: " But for them to try to take a pandemic and seemingly hope that it comes here, and kills millions of people so that they could end Donald Trump's streak of winning, is a ne...

Re: Silly questions

Nice! Another proof that, on the whole line, the density -> 0 as tau -> 1.

Plus, shows the answer is the same (0) in D dimensions!

Re: Silly questions

Well, if my solution is correct, the Green function cannot be continued beyond [$]\tau = 1[$], so there is an issue there.

Re: Silly questions

Pretty sure: in 1D, the transition density [$]p(x,t)[$], starting from an arbitrary density at t=0, converges to 0 for all real x, as [$]t \uparrow 1[$]. Loosely, all the mass went to [$]\pm \infty[$].  Proof: the Green function [$]G(x,T|x_0) \propto \frac{e^{-(x-x_0)^2/(2 v_T)}}{\sqrt{v_T}}[$], whe...

Re: Proof for square-root-of-time rule

@mathdude,
 bearish's iid argument is rigorous as long as you interpret "returns" as [$]x_t = \log S_t/S_{t-1}[$], and the variance of [$]x_t[$] exists.

Re: Trump -- the last 100 days

Thanks, Alan.  Mulling it over. :D What comes immediately to mind is ppauper, actually, and the photo he liked to post whenever writing about AOC, e.g.,: ppauper:  the "democratic socialists" are fighting amongst themselves. Sandy Ocasio wants to tax the rich at 70% https://cdn.cnn.com/cnnnext/dam/...
