Win-Vector LLC has been offering a couple of online video courses on the topics of data science and A/B testing (both using R). These are high quality courses and well worth the money and time needed to work through them closely (with all materials distributed on GitHub).
Win-Vector LLC is proud to announce the R data science value pack. 50% off our video course Introduction to Data Science (available at Udemy) and 30% off Practical Data Science with R (from Manning). Pick any combination of video, e-book, and/or print-book you want. Instructions below.
