Learning outcomes

Upon completing the course, the student can carry out statistical inference for numerical and boolean data. The student can recognise situations where standard data models (normal, binomial, linear regression) can be applied. The student can compute, interpret and explain statistical summaries, including posterior probabilities and credibility intervals.

Content

Content Core content Complementary knowledge Specialist knowledge
1. descriptive statistics: graphics (dot plot, histogram, box plot) and summary measures (sample mean, median, variance, standard deviation).   empirical cdf, QQ plot, sample range, interquartile range, alternative definitions for median and quantile, percentile  variational characterisation of mean and median, Chebyshev's inequality, Samuelson's inequality, Jensen's inequality 
2. Inference on a discrete parameter: Bayes' law, the elements of statistical inference (sampling model, likelihood, prior, posterior)  false detection rate & missed detection rate, binary symmetric transmission channel, medical testing  base rate fallacy; randomized response, Monty Hall 
3. Inference for proportions: single proportion (beta prior, posterior, 95% credibility interval, predictive distribution), comparing two proportions (normal approximation); Bernoulli & binomial distributions  simulation, recursive update, equivalent number of observations  Laplace's law of succession, decision theory, mathematical derivation of formulas 
4. Inference for means and variances: one population (marginal of mean, predictive distribution), two populations with equal variance, with unequal variance (normal approximation); distributions (normal, t, gamma)  MAP estimate, simulation, paired observations, marginal precision, model checking using predictive distribution, scale invariance of reference precision prior  recursive update, mathematical derivation of formulas 
5. Simple linear regression: normal sampling model, posterior distribution of regression coefficients, posterior predictive distribution; regression with transformed variables  least squares fitting, coefficient of determination, regression through the origin  physical analogy of least squares line; proof of 0<= r^2 <=1 
6. Inference for correlation: bivariate normal sampling model, posterior distribution of r based on atanh approximation  correlation coefficient and width of standardized variable ellipse, model checking using simulation, correlation does not imply causation  mathematical derivation of formulas 
7. Doing statistical analysis using Matlab or Octave
