Reasoning behind multiple names for the equivalent risk measures AVaR/ETL/ES/CVaR Possibly the biggest road block to learning statistics are the varied and nonsensical naming. “[...]bad names reflect (or even result in) difficulties in understanding.” Hurst, Joseph, colours and noises: The importance of names in an important natural behaviour, Demetris Koutsoyiannis itia.ntua.gr/getfile/792/1/documents/… |

Square root of time “without a change of model”, I agree, and a simple example would be to change your scale to a 10 day bar + a probability weight. “P.

How to perform Empirical Mode Decomposition? There is inherent massive lag in the calculation of the Hurst exponent (H), maybe this is your problem? How are you using EMD in your strategy, what method of EMD are you using, do you plan to use EMD in real time? FYI: I'm in the process of reinventing IMF part of the EMD method, specifically for capitalized markets for real time use. |

Fastest algorithm for calculating retrospective maximum drawdown Your question is not clear to me. Do you mean the easiest technique to code, or code that is CPU efficient? |

Monty Hall Model 3 days vs. 3 choices of the market direction plus market moving news, I don't think this is the same problem as what the Monty Hall problem is about. Monty hall only had 2 rewards a goat and a car, and 3 doors to choose from. I think you need to re-model the concept of what is a door, and what the 2 rewards are behind the 3 doors. I think you need to eliminate the flat position, and you only need to work with one day (Tuesday), leaving you with 2 rewards (goat/car, long/short). |

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. |

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. |

Proxy for a trigonometric angle function 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. |

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. |

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? |

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 |

How do you synthesize a probability density function (pdf) from equally weighted price data? @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? |
