Course content

The course starts with a short revision of data exploration and multiple linear regression models. A non-technical introduction of generalised additive models (GAM) is provided. GAMs will be used to estimate long-term trends, seasonal patterns, covariate effects, and auto-regressive correlation. We also provide a short introduction to linear mixed-effects models and generalised linear mixed-effects models (GLMM) to analyse hierarchical data (e.g. short time series from the same core or site). GLMMs and GAMMs are used to estimate trends, seasonality, and covariate effects in multivariate time series. For a more detailed description, see:

GAMMs are applied on continuous, binary, proportional, and count time series data using the Gaussian, Poisson, negative binomial, Bernoulli, binomial, beta, gamma, and Tweedie distributions.
