Data smart: using data science to transform information into insight

Everything you ever needed to know about spreadsheets but were too afraid to ask

Cluster analysis part I : using K-means to segment your customer base

Naïve Bayes and the incredible lightness of being an idiot

Optimization modeling : because that "fresh squeezed" orange juice ain't gonna blend itself

Cluster analysis part II : network graphs and community detection

The granddaddy of supervised artificial intelligence : regression

Ensemble models : a whole lot of bad pizza

Forecasting : breathe easy; you can't win

Outlier detection : just because they're odd doesn't mean they're unimportant

Moving from spreadsheets into R.
