 Feb 5 awarded Yearling Jun 8 awarded Constituent Jun 8 awarded Caucus Dec 7 comment Linear interpolation @Aabaz you should post that as an answer Dec 11 awarded Quorum Dec 9 awarded Precognitive Dec 2 comment What does -1.13 times faster mean? How does that notion of direction make sense in terms of execution speed? I'm with @Skilldrick here -- the intended interpretation is probably -1.13 = 1/1.13 but basically the graph is wrong. Oct 25 comment An occupancy problem Might also be worth asking this on stats.SE -- not to suggest it's at all off-topic here, just to increase the number of possible answerers. Oct 15 accepted Characterising a function involving the max and min of other functions Oct 13 comment Characterising a function involving the max and min of other functions Yes, that's exactly it. There's some physical rationale for that choice, but it's fairly dubious. Oct 13 comment Characterising a function involving the max and min of other functions Doubtless you are correct, but this identity becomes rapidly less useful with more functions. I think that part of the problem is that at any particular x only two functions contribute to the result, but exactly which two varies. I'm starting to suspect that only relatively trivial general predictions can be made and everything else will depend very closely on the exact functions involved. Oct 13 asked Characterising a function involving the max and min of other functions Oct 5 comment How do I apply a Gaussian Blur (low-pass filter) to an image made up from a set of points? Although Justin's answer is phrased in terms of "pixels", what he describes is a 1d filter suitable for use on a list of values. You can apply such a filter to your X and Y values separately (considering the two dimensions as sampling independent functions of t) and the result will be a smoothed point list. Aug 27 comment What is Modern Mathematics? Is this an exact concept with a clear meaning? @J. Seems. But I'll admit it's close. And what's all this I'm hearing about a popular beat combo named after some kind of arthropod? Aug 27 comment What is Modern Mathematics? Is this an exact concept with a clear meaning? @Qiaochu Being "modern" is so old hat. Nowadays everyone wants to be "hip" or "groovy" or "with it" or "fab"... Aug 26 answered Combine n Normal distribution Probability Sets in a limited float range Aug 19 comment Why is $22/7$ a better approximation for $\pi$ than $3.14$? You'd be constantly confused in supermarkets? Aug 19 awarded Enthusiast Aug 17 comment Is there a simple test for uniform distributions? The OP explicitly states that chi-square is too complicated, although that does seem a little like a counsel of despair...
