Discrete Random Variable Course
This course equips you to handle discrete random variables for count data analysis. You will construct empirical pmfs, fit and validate Binomial, Poisson, and Negative Binomial distributions using MLE and moments methods, perform goodness-of-fit tests like chi-square and rootograms, assess overdispersion, quantify uncertainty, and transform probabilistic results into actionable business recommendations with real-world applications.

What will I learn?
Gain expertise in discrete random variables through this targeted course, progressing from data gathering and empirical pmfs to selecting, fitting, and validating Binomial, Poisson, and Negative Binomial models. Compute essential probabilities, analyse count data, evaluate model fit, measure uncertainty, and convey practical insights to stakeholders with business-focused examples.
Elevify advantages
