What will I learn?
Master discrete random variables with a focused course that takes you from data collection and empirical pmfs to choosing, fitting, and validating Binomial, Poisson, and Negative Binomial models. Learn to compute key probabilities, summarize count data, assess goodness-of-fit, quantify uncertainty, and clearly communicate actionable findings to stakeholders using practical, business-oriented examples.
Elevify advantages
Develop skills
- Model count data: fit Binomial, Poisson, and Negative Binomial fast and reliably.
- Estimate parameters: apply MLE and moments to real-world purchase count data.
- Build empirical pmfs: design samples, summarize counts, and visualize discrete data.
- Validate models: run chi-square tests, rootograms, and overdispersion checks.
- Translate probabilities: turn churn risks and zero-purchase rates into business actions.
