Predictive Analytic Evolution of R

Have had a number of talks with industry leader about R and its potential. At least they have heard of it now, but are still nervous about how it fits into their needs, except in the most specialized of circumstances.  And how does it interact with common software solutions they already have?  Key questions for the promotion of analytics.   Information Management explores its evolution.

Advanced Maths Win Wall Street

A view of what used to be called 'rocket scientists' in Wall Street.  I recall going to the Santa Fe Institute and hearing a talk about this phenomenon,  just before the crash.   Now its math, big data and analytics.  Its not that I do not believe in these methods, I just look at the predictive value with caution.  Note something new here, the use of forward-looking, unstructured data analysis to look for causal triggers.    As opposed to quant forecasting.

On Predictive Analytics

This piece makes the point that I often do ... that all analytics, all business decisions, are predictive. The word 'predictive'  includes the implication that the result may be imprecise, or even wrong. How do we manage that?
