Thanks Chukchi... interesting article!I also don't need Weil to get the answer for powers of 2...what is remarkable is that we have the same answer for powers of any other number (except powers of 10).

I was told that this problem was suggested by V. I. Arnold. Simple question: What is the probability that a given power of two starts with a digit 1? (e.g. 2^4=16, 2^7=128, 2^10=1024, ...).

<t>Hey guys!Just had a phone interview and was asked to solve the "dice problem" this thread is about....Here is my solution using conditional expectation: where X is a dice outcome and E[X1] = 3.5. The reasoning is the following: if the first outcome is less than the price of n-1 - step game, then ...

you might be right, but this problem is about math......not about plant biology. The point here is that intuitively, at the first glance, the answer seems absurd (at least for me).

haha Beavis...I know where you got this pic )

<t>Hello, smart people...Here is a funny brainteaser.The point is to solve it in you head, without using pen and paper...it's for high school children. You have 100kg of berries (blueberry, raspberry, whatever..). 99% of berries is water. ............................some time passed and some amount ...

<t>QuoteOriginally posted by: AaronThis was way to tedious to consider doing by hand, what's the challenge? I decided to program a solution. If you had to build a system to do a lot of these puzzles, you'd use an exhaustive algorithm, or maybe something clever. But I wanted something that would be q...

<t>QuoteOriginally posted by: NorthernJohnI am afraid that I can't remember from your previous posts what stage you are at, but if you are looking for your first position, it is definitely worth approaching the banks yourself.

I wanted to ask the same question...there is a big discount for LSE students on C++ Quant Finance course....and I am thinking about taking this course.I had some C++ experience quite a while ago, so I wonder if it would be usefull for my job hunt to have this certificate on CV.

<t>Hi,Question for competent people like NorthernJohn...I've talked to some headhunter today...he asked me kind of strange question...-To which banks I have applied to so far?-When I answered that I did not apply directly to banks and just sent my CV to recruiting companies... He told me to contact ...

Cass sucks.

<r>thanks guys.Chernov and that company at Columbia (Johannes etc. <URL url="http://www-1.gsb.columbia.edu/faculty/mjohannes/">http://www-1.gsb.columbia.edu/faculty/mjohannes/</URL>) use MCMC, particle/practical filtering for estimation...and deal with continuous time models...where simple estimatio...

<t>By the way....why not model jumps in this case like this where Y is now some distribution which may take positive and negative values but skewed to the right (since positive jumps are larger than negative). We could use Generalized Lambda Distribution and adjust parameters so it fits the data... ...

<t>Sorry, I didn't notice your answer. Thanks a lot!However, I dont know why you call it -approx- MLE....as I understand in case when we have at most one jump per day (considering daily data) we can use ordinary MLE. The problem with MLE for continuous tim models is that we may have infinite number ...
