Built a model that predicts with 97.4% estimated accuracy how well a gym-goer performs dumbbell sets, returning class A for correct form and classes B to E otherwise. The model exhibited 95% accuracy when tested across a set of 20 new observations. [STUDY]
Executive summary. Wearable devices such as Nike’s FuelBand and Fitbit have made it possible to collect a large amount of data about how much we exercise. However, relatively little attention has gone towards measuring how well we exercise. We build a model that predicts with 97.4% estimated ...

Excellent guide to optimizing your R code for greater speed and efficiency.
Optimising code to make it run faster is an iterative process: Find the biggest bottleneck (the slowest part of your code). Try to eliminate it (you may not succeed but that's ok). Repeat until your code is “fast enough.” This sounds easy, but it's not. Even experienced programmers have a hard ...

How to get faster and more robust results when AB testing your online advertising campaigns.
Traditional hypothesis tests aren't suited for online ad copy testing because they require a fixed sample size for every ad combination. See how advances in statistics remove that requirement, and leverage real-time data to deliver more robust results faster. Getting your sample size right is hard enough across one ad group, let alone millions of ad groups. If your test runs across too few impressions, your test could fail to uncover a statistica...
