Explore Bayesian statistics with Ox educ's online course, covering essentials from marginal probabilities to practical inference examples in various contexts.

Course Description

Embark on a journey into Bayesian statistics with this comprehensive online course offered by Ox educ, ideal for those looking to deepen their understanding of statistical methodologies. Delve into various aspects of marginal and conditional probability for continuous variables.

The course introduces Bayes' rule, offering both a derivation and intuitive explanation. Explore its application in statistical inference, from understanding likelihoods, priors, and denominators to real-world examples like posterior distribution.

Grasp the concept of exchangeability and its significance to independent identically distributed (iid) variables. Learn about the intricacies of Bayes' rule's denominator for discrete and continuous variables, and why likelihood isn't a probability.

Discover sequential Bayes and data order invariance, and familiarize yourself with conjugate priors, Bernoulli, Binomial, and Beta distributions. Witness Bayesian inference in action with a thorough examination of disease prevalence cases.

Gain insights into predictive distributions, examine normal priors, likelihoods, and their conjugations, including examples with known variance and population mean test scores. Explore probability distributions like Poisson and Gamma, and see real-world examples in crime count modeling.

The course provides a full spectrum of Bayesian inference concepts and applications, laying the groundwork for practical understanding and application in various fields. Ideal for students and professionals in basic studies wanting to enhance their statistics knowledge.
