comment Monty Hall Model
Your assuming that manager A is an agent of Monty Hall (all knowing), and has exposed a goat behind door number 1, which is a long position. The flat position is not a viable option as you stated there is a breakout due on Tuesday, so you can eliminate it (but do you reassign the probability weight, and if so to what?). So you assume that long positions are goats, and you take the short position.

comment Proxy for a trigonometric angle function
@chrisaycock I need a function that will capture the estimation of the Hurst exponent without using the linear regression slope calculation.

tks, and I was thinking that this might be the wrong forum for this Q. I don't see that I have control over deleting my post.

comment Proxy for a trigonometric angle function
@chrisaycock Time based financial calculation that requires a slope calculation are suspect. I'm looking for a stable/robust representation for the slope component of the slope-intercept form. Angle calculations using market data are nefarious to work with, as market compression rescales nonlinear. I'm working with the Hurst exponent, it utilizes the slope-intercept form to characterize the market.

comment Hurst Exponent Calculation
I just started calculating the Hurst exponent a few days ago using OpenOffice. I've been looking for examples as well to help me finish it, no luck so far. Post your study if your able, it will help me, and maybe someone can make the necessary corrections?

comment Can the Hurst exponent be greater than one?
Testing software to estimate the Hurst exponent can be difficult. The best way to test algorithms to estimate the Hurst exponent is to use a data set that has a known Hurst exponent value. Such a data set is frequently referred to as fractional brownian motion (or fractal gaussian noise). As I learned, generating fractional brownian motion data sets is a complex issue. At least as complex as estimating the Hurst exponent. bearcave.com/misl/misl_tech/wavelets/hurst/index.html

@AlexeyKalmykov I don't have enough credits to use the chat room to directly ask for help. FAQ does not address how a new member should respond. Some one voted that there is an answer to my question, there is only a good suggestion (one that I'm working on tks!). How do I change to not ans? I'm looking for a method of how to create a (pdf) utilizing density estimation with real world price data. Since the question has been answered, should I resubmit my problem, but with a different title and I'll included the knowledge gained from vanguard2k with a slightly different angle and questions?
