Closed form for geometric average option

<t>I try obtain a closed form for a geometric average option with fixed strike following the methodology of PDE. I get bogged down in the equation with non-constant coefficients (after two changes of variable), depending on t, and I don't which is the change of variables suitable to obtain a equatio...

Hulls algorithm for Asian options

Anybody knows a paper in the web in which explains the algorithm for valuation Asian options with a binomial tree. I get the Hull's book, but isn´t explicitly this algorithm.Thanks and best regards

Simulating 2 variables with different DF.

I have 2 random variables, E and F. E is distributed like Weibull and F like gamma. Which is the most suitable correlation coefficient between them?Can i use the Pearson coefficient? How can i simulate both of them? Thanks a lot

how can i separate aggregated data?

I have a sample of banks which have data aggregated, for instance: 170 Banks and one only gross income, how can I separate this data? I suppose that the individual gross income don't available for me, i have to be estimated them. Do you know any statistical process?

Finding a likehood of a mix distribution

First of all, very thanks. What I meant with my equation is your second posibility: p*1(x)+(1-p)*1(x>0)*f(x). I know what you mean and I didn't think about this possibility although I wonder if is there any analitycal expression for likehood function of this function.

Finding a likehood of a mix distribution

<t> I have a easy problem but I can´t solve it, maybe i don´t think about it too. Well, I have a mix distribution, it means, this one has a discrete part and a continuous part, for example:f(x)= p*I(x=0)+(1-p)I(x>0)f(x)where p is a parameter of the distribution. It is between zero and one, it's a pr...

MonteCarlo Markov Chain

First of all, a lot of thanks!! Google was my first attempt, but all the links that it shows me were unuseful, i need anything about methodology: concepts and algorithms from a math perspective. Thanks.
