Re: Trump -- the last 100 days

Trump has a weird goal with DACA. Apparently he wants to overturn it to turn it into a bargaining chip. Not a good strategy at this point -- if ever.  
A little vague, but better

Re: Absense of data is creating markets in 'suspended animation'

methinks you might be  contradicting yourself . Anyway, the very ugly  Q2 GDP will roll in on schedule, and mostly be properly ignored.    Or, maybe the market will rally on the release because the data will show why the economy cannot be locked down that way again.  :D If you just need to see some ...

Re: Differential equation with a random walk forcing

I don't know much about fBm, but  --- I think a lot of the motivation has to do with the decay of the autocorrelation function of the stochastic process.  Typically (but not always), processes that are (noise) driven by standard Brownian motion increments have exponentially decaying autocorrelation ...

Haha -- was not aware of the Church of the FSM -- got lots of laughs at their wikipedia page!

Re: Trump -- the last 100 days

As Trump and Republican governors (and, in the case of California, mayors) kill tens of thousands of people by ignorance and negligence, he is panicking about looking good. Thus the quest to reduce the amount of testing being done. Fewer tests, fewer positive cases being reported! And no, that was ...

Re: Differential equation with a random walk forcing

Just thinking out loud, the next issue that interests me is: how to write a numerical solver for the full problem? (To get solutions accurate even for large [$]\rho[$]).  I would start by thinking of [$]Q(t)[$] as just some given, single-valued, continuous function that starts at [$]Q(0) = 0[$]. Dra...

Re: Differential equation with a random walk forcing

The most I can come up with is two terms of a formal perturbation solution  -- in powers of [$]\rho[$].  I'll suppose the spatial domain is the whole line and there is an initial function given at t=0, but no boundary conditions. If [$]\rho = 0[$], suppose the PDE solution to that initial value prob...

Re: Trump -- the last 100 days

This is what's at stake in November. From the twit himself:   " These horrible & politically charged decisions coming out of the Supreme Court are shotgun blasts into the face of people that are proud to call themselves Republicans or Conservatives. We need more Justices or we will lose our 2nd. Am...
