Statistical Theory I
The aim of the module is to extend your knowledge of statistical theory and its applications to introduce you to some of the basic methods of statistical inference and estimation, which are needed in data analysis. The aim will be achieved through a mixture of theory and practice.
At the end of the module you should be able to...
- be practised in the use and manipulation of standard density and distribution functions of both discrete and continuous random variables;
- be acquainted with the concepts of joint and conditional distributions and the distribution of functions of random variables.
- understand the use of moment generating functions and their use in proving the Central Limit Theorem, and to see this in use with, for example, Poisson and exponential random variables;
- comprehend the usefulness of the normal distribution in aiding the calculation of the distribution of certain functions of the data, for instance sample means and variances, and the t-ratio;
- understand the most basic concepts of statistical inference;
- know about convergence in probability and convergence in distribution;
- be able to perform basic statistical inference on the parameters of standard distribution functions, including estimation of parameters using several methods, construction of confidence intervals (with a brief mention of hypothesis tests).
