Data regression analysis

People will obtain many relating data of two or more than two dimension during experiments and production. These data will help them to solve problems of reality on contrary, which need data processing to make them become mathematicalematical model reflecting the data variation regulation. The application of the Least Square Method can only make linear regression, but to the nonlinear problems it must construct relating mathematicalematical relationship expression, namely mechanism model… Continue

Going From a Theory of Error to a Web Analytics Process

By Gary Angel



My post on “Numbers it’s better NOT to know” got me thinking more closely about the relationship between a theory of error and the types of web analytic process organizations should adopt. That led to a more considered post “Defending the Indefensible” where I laid out some of the most common causes of error and talked a little bit about how these errors should influence our thinking about organization and process.

Analyzing the Question - How Covered Are We?

When your career hinges on ensuring coverage over regulatory compliance, you will appreciate the common curse that is had when asking, "how covered are we?".
