Re: Offer of consulting services
Remember that, while you may ask for help to solve the problems in question, you have to provide a personel contribution. To answer your last question, yes, a simulation would do.

Random Walk
In a random walk with state space = Z and transition probabilities P(k --> k+1)=p, P(k --> k)=r, P( k --> k-1)=q with p+q+r=1, the expected number of steps before moving up is either finite or infinite depending on p, q, r. This means (applied to the stock market) that it is possible for a stock price to never surpass its present value. I am looking for a proof that someone with NO mathematical background could understand. Tthe easiest proof I have so far requires knowledge of recurrence relations and basic arithmetic (+, -, *, /). I would like to put this proof on my financial web site. The author of the proof would be acknowledged. Thank you.

distribution of daily low/high
The problem is to find the (parametric?) distribution of the ratio low/high in connection with Brownian motions. The application I have in mind is daily low/high or 52-week low/high for any particular stock price. I would like to add a result on this subject in my section "theorems" on my web site. I've been thinking of adding a graph of these distributions, obtained by simulation, but if someone has something better (a theoretical result or a good reference), I would acknowledge her contribution. I am also interested in extreme value theory applied to the stock market.

mathematical artwork
Interesting mathematical creations. They are not fractals. It's produced with pretty simple functions, and does not require recursive computations. Actually, some of these objects are very similar to fractals - but again do not involve recursive formulas. Some other images are clearly not fractals, but instead exhibit original textures (like wool cloth or carpet). http://www.datashaping.com/artwork.shtml = Instructions for joining and leaving this list and remarks about the problem of INAPPROPRIATE MESSAGES are available at http://jse.stat.ncsu.edu/ =

Reach and Frequency
An advertiser purchases online Ad impressions and wants to achieve a certain reach over a specified period of time. How many impressions does he have to purchase? The page-per-user distribution is known. I've published a solution on my web site, at datashaping.com/internet.shtml. However, I am wondering if more general results are available. Thanks.
