What will I learn?
Master discrete random variables through a focused course progressing from data collection and empirical pmfs to selecting, fitting, and validating Binomial, Poisson, and Negative Binomial models. Compute key probabilities, summarise count data, assess goodness-of-fit, quantify uncertainty, and communicate actionable findings to stakeholders with business-oriented examples.
Elevify advantages
Develop skills
- Model count data: fit Binomial, Poisson, and Negative Binomial reliably.
- Estimate parameters: apply MLE and moments to purchase count data.
- Build empirical pmfs: design samples, summarise counts, and visualise discrete data.
- Validate models: run chi-square tests, rootograms, and overdispersion checks.
- Translate probabilities: turn churn risks and zero-purchase rates into business actions.
