New Ideas to Forecast Stock Market Trends

My interest has mostly been in trading QQQQ and other major indexes, hoping to build a small portfolio of contrarian (negatively correlated) indexes. I am interested in two types of strategies:

1. A strategy where some cash is dormant on a trading account for most of the time, yielding a return of less than 4% a year when in "dormant mode". Once in a while (it could be every two or three years, sometimes every six months), when large movements occur on the stock market, I step in as… Continue

What is Six Sigma?

The concepts surrounding the drive to Six Sigma quality are essentially those of statistics and probability. In simple language, these concepts boil down to, “How confident can I be that what I planned to happen actually will happen?” Basically, the concept of Six Sigma deals with measuring and improving how close we come to delivering on what we planned to do.

Anything we do varies, even if only slightly, from the plan. Since no result can exactly match our intention, we usually… Continue

Bayesian Mark Recapture for Small Sample Sizes

3/10/08

I gave a short seminar at National Marine Fisheries Services NMFS in Honolulu, Hawaii, entitled "Bayesian Mark-Recapture for Small Sample Sizes"

SUMMARY.

Mark-recapture methods are often used to estimate the abundance of rare or elusive populations but produce highly uncertain results when sample sizes are small. We develop a new estimator for a single-release, single-recapture experiment based on Bayesian methodology to handle this situation. The number of marked… Continue

Source code for Robust Ridge and Linear Regression with Bootstrap

Works well with non Gaussian data or outliers. Allows you to set up bounds on the regression parameters (similar to ridge regression). Does not use matrix inversion, thus numerically stable. Robust parameter estimation based on Monte-Carlo simulations and re-sampling. The source code can easily be modified to perform logistic regression. This package can be used by scientists, programmers, analysts or engineers with limited statistical knowledge. Works on Unix, Linux or Windows. We will help… Continue

Data Mining Definition

Having read from great authors and researchers, I had always taken the definition of data mining for granted. Following the tradiitons of Occam's Razor, I tried to summarize one myself but felt the difficulty of covering the entire spectrum of data mining which is ever evolving. Anyways, here is my try...

Data Mining is a process of extraction of non-trivial patterns from massive datasets which either provides descriptive insights of the data (not perceived without this… Continue

Certified Analytic Professional

What does Data Shaping mean?

The term was created in 1999 to fill a gap between data mining and statistics. Data shaping is about employing advanced statistical techniques to problems usually handled by computer scientists (machine learning, knowledge discovery, artificial intelligence, web mining). A data shaper is a true software engineer or computer scientist, and a true statistician at the same time, capable of extracting actionable information from large data sets, in… Continue

Spatial analysis and archeology

I presented a seminar at School of Fisheries and Ocean Sciences at University of Alaska Fairbanks.

SUMMARY: GIS maps reveal that archeological sites in the Gulf of Alaska region are highly clustered. Crowell et al., has suggested that clustering of sites is driven by spatial patterns of 24 marine resources. These resources are known to be important from bone fragments found at archeological sites and also from oral histories. We constructed a data base of subsistence resources… Continue

Course: Spatial Statistics With GIS

By Dr. David Unwin

Aim of Course:

For centuries, geographers have laboured to discover and document our planet. Along the way they have used a variety of analytical techniques and drawn a variety of different types of map, but, by and large, this work has been conducted in isolation, without significant impact on the worlds of other sciences, commerce and industry.

The world discovers "geography": With the development of computer-based…
