Increasing customer loyalty using data analytics

Loyalty Marketing has become a key strategy for most companies in today's competitive marketplace. The practice is based on a very simple premise - as you develop stronger relationships with your best customers, they will stay with you longer; the longer they stay, the more profitable they become.

Nonparametric regression: the LOESS procedure

PROC LOESS implements a nonparametric method for estimating local regression surfaces pioneered by Cleveland (1979); also refer to Cleveland et al. (1988) and Cleveland and Grosse (1991). This method is commonly referred to as loess, which is short for local regression.



PROC LOESS allows greater flexibility than traditional modeling tools because you can use it for situations in which you do not know a suitable parametric form of the regression surface. Furthermore, PROC LOESS is… Continue

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

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

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

Course: Spatial Statistics With GIS

By Dr. David Unwin

Aim of Course:

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…

2008 Statistical Resolutions

The biggest challenge of 2007 for statisticians was the pressing demand for real-world explanations and applications of statistical concepts. On one hand, statisticians found relief in not having to focus so much of their time on inspiring trust in the number-crunching methods. A techno-driven quasi-dependence on quantitative intel set such concerns on the back-burner. On the other hand, businesses and consumers united in expressing a supposedly simple request -- "Ok, so show me how I can USE… Continue
