Business users must be empowered by true data…Continue

As a decision analyst, it is delightful to see all the excitement about the ever-increasing amounts of data available. But, when I see much of what data scientists are doing to find interesting patterns (descriptive analytics is just looking in the rear view mirros) and forecasting (predictive analytics, ideally our GPS), I see little attention paid to the real business decisions that might be informed by these insights (the decision analytics, helping our clients steer a better…Continue

Hi All ,
I've recently build a predictive data model for a campaign to target group of customer who can switch from payment method "A" to Payment method "B".
The idea was to come up with predictive model with payment/usage variables as independent variable and the event of switch in past is taken as dependent variable.
i) I used logistic regression model for probability estimation.
ii) The data is sorted in order of descending probability…Continue

Ever wondered why certain countries have certain colors in their flags, why it has certain symbols and what are the different patterns?
We started digging through, checking a Wikipedia article on this topic.
