Tables of Correlation Features Useful for data mining and analysis
Tables of Correlation Features - These tables of correlation features are presented for the convenience of analysts and for use with statistical and practical significance tests. Now you can quickly discriminate between correlation coefficients and their statistical or practical significance.
Correlation Coefficients A tutorial to dispel SEOs quack "science".
A tutorial on Correlation Coefficients - This is a three-section tutorial on correlation coefficients. Section one discusses the proper way of computing r values. Section two describes statistical applications. Section three discusses recent research on the problem of correlation coefficients as biased estimators.
Standard Errors! A tutorial that any Web miner should read.
A Tutorial on Standard Errors - Every statistic from a sample distribution has a standard error that is specific to that statistic. Using the incorrect definition for a standard error invalidates any research study.
Fractals with a browser! And you thought this was not possible!
A Web Browser Approach to the Design of Fractals and Multifractals - The traditional way of constructing fractals is with computer algorithms. Some of these use pixel-by-pixel drawing techniques wherein the output of a recursive function is evaluated against a predefined condition. Other strategies or combination of techniques use HTML tables, image files, VML, SVG, or the canvas tag introduced in HTML5. In most cases, implementing these strategies and techniques involves a learning curve, requires of a large number of iterations, and consumes server resources. The purpose of this article is to present an alternative to the design of fractals that does not require of any additional software or special resources, but of a Web browser that supports CSS and XHTML. Classic fractals as well as Sierpinski Carpets generated with Mann Iteration Method and probabilistic methods are reproduced. The impact of CSS sub-pixel rounding errors on the patterns, and caused by five different browsers, is documented. End users can test the proposed approach by downloading the corresponding Fractal Source Codes to their local machines.
