Courses

• Statistics for Data Science and AI: Describe data, reason with probability, and test ideas with confidence intervals, hypothesis tests, regression and A/B tests, in Python with pandas and SciPy. (Beginner, about 10 hours)
• Foundations of Probability and Statistics: Build the probability that data science rests on: rules and counting, Bayes' theorem, discrete and continuous distributions, expectation and inference, derived, calculated and checked by simulation. (Intermediate, about 14 hours)
• Practical Statistics for Data Scientists: Apply statistics to real decisions: robust summaries, the bootstrap, A/B tests done properly, regression with diagnostics, and logistic models judged by the costs of their errors. (Intermediate, about 15 hours)
