Discrete Random Variable Course
This course equips you to handle discrete random variables for practical count data analysis. You will learn to construct empirical pmfs, fit and validate Binomial, Poisson, and Negative Binomial models using MLE and moments methods, perform goodness-of-fit tests like chi-square and rootograms, quantify uncertainty, and convert probability results into straightforward business decisions and actions.
