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, exploratory and confirmatory analysis.
- Probability distributions: dependence and independence, multivariate Gaussian, Poisson, Dirichlet, random number generation and simulation of distributions, simulation of samples (bootstrap).
- Predictive models: linear and logistic regression, and Bayesian classification.
- 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, estimation of model performance.
On successful completion of this unit, students should be able to:
- perform exploratory data analysis with descriptive statistics on given datasets;
- construct models for inferential statistical analysis;
- produce models for predictive statistical analysis;
- perform fundamental random sampling, simulation and hypothesis testing for required scenarios;
- implement a model for data analysis through programming and scripting;
- interpret results for a variety of models.
NOTE: From 1 July 2019, the duration of all exams is changing to combine reading and writing time. The new exam duration for this unit is 2 hours and 10 minutes.
Examination (2 hours): 50%; In-semester assessment: 50%
Minimum total expected workload equals 12 hours per week comprising:
- Contact hours for on-campus students:
- Two hours lectures
- Two hours studio
- Additional requirements (all students):
- A minimum of 8 hours of personal study per week for completing lab and project work, private study and revision.
