This unit explores the statistical modelling foundations that underlie the analytic aspects of Data Science. It covers:

  • Data: collection and sampling, data quality.
  • Analytic tasks: statistical hypothesis testing, introductory decision theory, exploratory and confirmatory analysis.
  • Probability distributions: multivariate Gaussian, Poisson, Dirichlet, linear and logistic regression, random number generation and simulation of distributions, simulation of samples (bootstrap). Estimation: parameter and function estimation, maximum likelihood and minimum cost estimators, Monte Carlo estimators, inverse probabilities and Bayes theorem, bias versus variance and sample size effects, cross validation.
  • Information Theory: information and entropy, data coding and compression, entropy and likelihood, relative entropy and correlation, bounds and limits.
  • Dependence models: Markov model, Bayesian and Markov network, log-linear model.
  • Modelling: hypothesis testing, inference, and optimal decisions, predictive versus generative modelling, experts and assessing probabilities and models.


On successful completion of this unit, students should be able to:

  1. compare the general roles of exploratory, confirmatory and decision analysis as applied to data;
  2. explain how the source and providence of data affects analysis;
  3. summarise the role of domain experts in supporting analysis and the difficulties they may have;
  4. implement a computational model for statistical analysis of simple problems and construct an evaluation methodology for the results;
  5. compute statistical factors and diagnostics on simple problems such as entropy, likelihood, correlation, and independence;
  6. interpret the challenges involved in estimation from data, and implement the methods used on simple problems;
  7. describe basic methods of random sampling, simulation, and hypothesis testing.
