No. 18: Analytics, Fast and Slow

Fast to the wrong answer is not a good business or scientific strategy. Slow, but rigorous, analysis does not meet business or scientific needs either. It has to be "and."

No. 17: Analytics, Data Science and Statistics – A Rose by Any Other Name …

There is a lot of confusion over what data science is and how it is the same or different from statistics or other data analytic fields such as epidemiology or econometrics. This is my attempt to describe the "big tent" of Analytics.

No. 16: Beware Caesar – Alcohol Consumption and Alzheimer’s Disease

Published research from respectable journals and reported by renowned press outlets can be very misleading and of questionable importance. But it helps keep funding for the researchers and readership for the news media.

No. 12: Models – Implicit and Explicit

If we fail to acknowledge that we have biases and assumptions that influence our assessment of 'objective facts,' then we delude ourselves. Our perception of reality and how we judge evidence is colored by our beliefs which arise from our specific experiences.

No. 11: Some Beliefs in Priors

The probability that the null hypothesis is true is 0.50. How should we interpret that and then write it down mathematically?
