- Please note that this is not a self-study course.
Brief outline
We begin with an introduction to R and provide a protocol for data exploration to avoid common statistical problems. We will discuss how to detect outliers, deal with collinearity and transformations.
An important statistical tool is multiple linear regression. Various basic linear regression topics will be explained from a biological point of view. We will discuss potential problems and show how generalised linear models (GLM) can be used to analyse count data, presence-absence data and proportional data. Sometimes, parametric models (linear regression, GLM) do not quite fit the data and in such cases generalised additive models (GAM; a smoothing technique) can be used.
During the course, we will discuss Gaussian, Poisson, negative binomial, and Bernoulli GLMs and GAMs. The course website contains a bonus module with on-demand video files discussing Tweedie, Gamma, binomial, and beta GLMs (with exercises).
