Behavioural data analysis using maximum likelihood in R (BDML01)
19 March 2018 - 23 March 2018£275.00 - £475.00
This 5-day course will involve a combination of lectures and practical sessions. Students will learn to build and fit custom models for analysing behavioural data using maximum likelihood techniques in R. This flexible approach allows a researcher to a) use a statistical model that directly represents their hypothesis, in cases where standard models are not appropriate and b) better understand how standard statistical models (e.g. GLMs) are fitted, many of which are fitted by maximum likelihood. Students will learn how to deal with binary, count and continuous data, including time-to-event data which is commonly encountered in behavioural analysis.
After successfully completing this course students should be able to:
- fit a multi-parameter maximum likelihood model in R
- derive likelihood functions for binary, count and continuous data
- deal with time-to-event data
- build custom models to test specific behavioural hypotheses
- conduct hypothesis tests and construct confidence intervals
- use Akaike’s information criterion (AIC) and model averaging
- understand how maximum likelihood relates to Bayesian techniques
Any researchers (from postgraduate students to senior investigators) interested in analysing behavioural data. Examples will be primarily from non-human animal behaviour studies, but the methods will also be applicable to many researchers studying human behaviour. The course is intended for those wishing to construct custom statistical models and for those wishing to better understand the workings of standard statistical techniques that use maximum likelihood methods (e.g. GLMs).

There will be a combination of lectures and practicals. Practicals will be based on the topics covered in the preceding lectures. Data sets for computer practicals will be provided by the instructors
Assumed quantitative knowledge
A basic understanding of statistical concepts (mean, variance, correlation, regression, ANOVA etc.) and probability.
Assumed computer background
Some familiarity with R. Ability to import/export and manipulate data, fit basic statistical models & generate simple exploratory and diagnostic plots.
Equipment and software requirements
A laptop/personal computer with a working version of R or RStudio. R and RStudio are supported by both PC and MAC and can be downloaded for free by following these links.
It is essential that you come with all necessary software and packages already installed (you will be sent a list of packages prior to the course) as internet access may not always be available.
