Bush is poised to resign in about two years

<t>Quote I mostly agree with you on stem cells, i am totally indifferent to gay marriage, and i fully agree with you that i'd compromise on those. But Matt, why would you vote for Kerry? The only reason i heard so far is that you think Bush made mistakes and he says "nucular" and Kerry hasn't made m...

Bush is poised to resign in about two years

<t>Quote Zerdna, MattCushman was speaking rhetorically. He does not yet care to understand. He assumes you don't even believe your own arguments and that they are rhetorical.He is not saying "Give me your reasons." He is saying "You know you don't really have any reasons, so just admit that you are ...

Bush is poised to resign in about two years

<t>....continued...I'm am simply puzzled by your "Who is Kerry" comment. What is particularly irritating about a discussion with a person suffering from your particular condition, farmer, is a quote like QuoteNo you can't. Left-wing people just don't, they expect unanimous approval, and are not sati...

Bush is poised to resign in about two years

<t>Farmer,You weren't the person I was addressing in my post. You see, I understand your particular case; you happen to have some chemical imbalances. I am trying to understand (yes, I am actually trying to understand them, I'm not pitying them, or anything else) what motivated the mentally heathy p...

Bush is poised to resign in about two years

<t>As presumably intelligent people (who are capable of understanding QF), can you explain exactly why you support Bush?Do you really think that America is safer under Bush than under Kerry? What about the nuclear proliferation issues, the fact that our borders are totally porous to container shipme...

Weighing judiciously

<t>Weigh 4 and 4. If those agree, you know its in the remaining 4. Weight two of those against two of the original 8 (we know all of the original 8 have the correct weight). If those agree, you know it's in the remaining two, if they disagree you know it's in those two from the second weighing. Now ...

Multiple Choice Questions

<t>It's impossible to beat 25%. Expectations are additive, even when the random variables are not independent. It's clear that any given strategy has an unconditional 25% chance of being correct on each question by symmetry. The fact that there is some complicated relationship between the probabilit...

R squared in Style analysis Project

<t>Not sure how you could get a negative R^2... it is R, squared, after all. You could get a negative correlation, R, though this would be unlikely (the only way would be to have severely bad constraints I think).How are you calculating R^2? You could be running into numerical issues if your R^2 is ...

the grainy chart

Measure theory.More to the point, how can you ever really observe which side is up? You can only decide that it (the up side) lies in, or does not lie in, certain subsets of sides that can be determined using a finite amount of information.

the grainy chart

farmer,Can you please explain to a guy who is too employed to have the time to meditate on the subject, what an "infinite coin" is? Also, it sounds like a nice thing to have, where can I get one for cheap?Best regards,Matt

the grainy chart

<t>Greg,I disagree with you. You aren't being told that one of the coins was heads... you're being told that the one you pulled out of the bag is heads.Think about the following two games. Both start we me flipping two coins and hiding them from you. You are allowed to ask me question about the coin...

WHAT IS A QUANT BRAINTESTER???

<t>How/and or WHAT (according to a PLETHORA of peer reviewed journals) is a quant brainteaser? How do you think prestigous researchers from IVY LEAGUE institutions (one of who won a MacArthur "genius" grant, and the other one the National Spelling Bee) could prove, without a shade of doubt, that wav...

Lack of Citation linkage

I agree that there is a subset that doesn't cite the literature... I just think that there is another subset that does cite (though maybe these people don't refer to their work as "econophysics").
