Description: This graduate level course covers methods used in environmental
epidemiology where the distribution of health outcomes and related exposures are
measured over both space and time. The course starts with an introduction to the basic
concepts of epidemiology and covers cases where risks vary over time and space.
Consideration will be given to both temporal methods, where the investigation is of
risks to health over time in a single area, and spatial methods, where the emphasis is
on changes in risk over space within a given time period. However, the scale and
complexity of modern investigations means there is a need to consider relationships
over both time and space simultaneously and therefore a requirement for sophisticated
methods whose development is an active area of risk in statistical science.
Outline: The main topics to be covered include:
 Types of epidemiological studies; cohort, case-control, ecological
 Measures of risk; relative risks, odds ratios, absolute risk, sources of bias,
assessing uncertainty.
 Bayesian statistics and computational techniques; Markov chain Monte Carlo
(MCMC), Integrated nested Laplace approximations (INLA)
 Regression models in epidemiology; Logistic and Poisson generalised linear
models, generalised additive models, hierarchical models, measurement error
models
 Temporal models; time series models, temporal auto-correlation, smoothing
splines
 Spatial models; point processes, area and point referenced methods, mapping,
geostatistical methods, spatial regression, non-stationary models, preferential
sampling
 Spatial-temporal models; separable models, non-separable models, modelling
exposures in space and time, correction for ecological bias.
Throughout the course, there will be a strong emphasis on the implementation of
models in practice and the application of the methods will be demonstrated by
example using the commonly available computer packages, including R, OpenBUGS
geoR, gstat and INLA.
Prerequisites: The course assumes a solid background in statistics, although the
required material will be briefly reviewed and graduate students in Statistics would
qualify. There will be no assumption of a background in epidemiology. If you are
Lab: Subject to the availability of space and the necessary support, we will have a
laboratory program of hands-on study. This will include an introduction to the
statistical packages with lab assignments based on them.
Evaluation: Final grades will be based on assignments, laboratory exercises, and
projects.
Textbook:Various options are under consideration, but none has been selected as the
outline was being prepared.
