To introduce estimation and hypothesis testing methods based on likelihood and other approaches.
Statistical methodology is concerned with taking the numerical information contained in a sample (the data) and using it to make statements (or inferences) about the population from which the sample is drawn. In that the sample provides incomplete information about the entire population, there is inevitably some uncertainty relating to any inferences made. The methods developed in this course unit not only acknowledge this uncertainty but seek to model it in a meaningful way.
Intended learning outcomes
On successful completion of this unit students will:
- have an understanding of the underlying theory;
- be able to use these techniques on simple data sets.
Future topics requiring this course unit
Third and fourth level Statistics course units.
- Parameter estimation: general framework and concepts, the likelihood function, maximum likelihood estimates and their properties, extensions to more than one sample and restricted estimation.
- Hypothesis testing: elements of a statistical test, possible errors, the power function, the Neyman-Pearson Lemma, uniformly most powerful tests, generalised likelihood ratio tests.
