## Basic Statistics

You will need this for the following Part III courses:

- Modern Statistical Methods
- Applied Statistics
- Biostatistics
- Time Series
- Monte Carlo Inference
- Statistics for Stochastic Processes
- Topics in Statistical Theory

Relevant undergraduate courses are:

### Reality check

- Basic probability theory, including common distributions such as Binomial, Normal, Poisson, Chi-squared, etc. See e.g. Basic Probability and official prerequisites page mentioned above.
- Basic Linear Algebra (basic facts about orthogonal matrices). You can check if you are at the required level by doing the following exercises: Statistical Modelling Example Sheet 1 (2014/15) Q 1, 2a, 5, Example Sheet 2 (2014/15) Q8a.
- Basic Real Analysis. You can check if you are at the required level by doing the following exercises: Past Exam Question Part Ia 2016 Paper 1 Q3, Part Ia 2012 Paper 1 Q3

### Prerequisites

Undergraduate statistics, including:

- Maximum Likelihood Estimation. Common examples, consistency and asymptotic normality.
- Hypothesis Tests and Confidence Intervals. Likelihood ratio statistics, Wilks' theorem,
*t*-tests and*F*-tests. - The Linear Model. MLEs, hypothesis tests, confidence intervals and extensions.
- Bayesian Statistics. Definitions, examples and comparisons with MLEs.

You can use the following exercises to check your present level and to guide your study.

- Part Ib Statistics Example Sheet 1 (2014/15) Q3, 8, 9, 10
- Part Ib Statistics Example Sheet 2 (2014/15) Q1, 2
- Part Ib Statistics Example Sheet 3 (2014/15) Q1, 4, 5, 9

### Useful books and resources
