Likelihood and Bayesian Inference

Learning Outcomes

Learning Outcomes

Having successfully completed this module you will be able to:

• Conduct likelihood inference for parametric statistical models, including estimating parameters, constructing large-sample confidence intervals and conducting hypothesis tests.
• Construct appropriate parametric statistical models for frequently encountered types of data.
• Derive the asymptotic behaviour of likelihood inference, including the asymptotic distribution of the maximum likelihood estimator and the log-likelihood ratio test statistic.
• Conduct Bayesian inference for parametric statistical models, including choosing a prior distribution, computing the posterior distribution in cases with conjugate and non-conjugate priors, and making predictions and decisions based on the posterior distribution.

• Examples of statistical models, including simple models for identically distributed responses and regression models.
• Likelihood: maximum likelihood estimation, score, information, Cramer-Rao lower bound and the asymptotic distribution of the maximum likelihood estimator.
• Large-sample confidence intervals.
• Hypothesis testing: Generalised likelihood ratio tests and asymptotic distribution of the log-likelihood ratio test statistic.
• Concepts of Bayesian inference: prior distributions, posterior distributions and using the posterior distribution to make predictions and decisions.
• Bayesian inference with conjugate prior distributions.
• Markov Chain Monte Carlo methods for approximate sampling from the posterior distribution.
