Not long time ago i have seen a presentation where a map of emotions from the web was created in real time by aggregating… Continue

This paper reviews the quantitative methods developed at selected authorities for stress testing credit risk, focusing in particular on the methods used to link macroeconomic drivers of stress with bank-specific measures of credit risk (macro stress test). Authorities with a mandate for financial stability are particularly interested in quantifying the macro-to-micro linkages and have developed specific modeling… Continue

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

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. Jacques Warren, whose comments certainly triggered some… Continue

?". The answer is never straight, nor simple, and generally results in wondering why you asked to begin with - ultimately it’s a judgment call. Readers may find some consolation knowing that there exists a large group of red-eyed, late-night, complex report-reading types that must make the same difficult decision, and seek to ensure… Continue

. We show that well chosen graphs combined with human brain interpretation is powerful to help with business decisions. We also show that simple but smart reporting, careful metric and data selection, when combined with appropriate visuals, provide higher efficiency than sophisticated statistical models. This is true even with the largest data sets, when data is seen through the eyes of a sharp data miner with a strong… Continue
