covariance and correlation
this video explains what is meant by the covariance and correlation between two random variables, providing some intuition for their respective mathematical formulations. check out https://ben-lambert.com/econometrics-course-problem-sets-and-data/ for course materials, and information regarding updates on each of the courses. quite excitingly (for me at least), i am about to publish a whole series of new videos on bayesian statistics on youtube. see here for information: https://ben-lambert.com/bayesian/ accompanying this series, there will be a book: https://www.amazon.co.uk/gp/product/1473916364/ref=pe_3140701_247401851_em_1p_0_ti
