This three-day course will teach you advanced topics in multilevel modelling. After taking this course, you should be able to analyse more complex multilevel models and to interpret and report the results.
This course builds upon the contents of the course 'Introduction to multilevel analysis'. It consists of three days with lectures in the morning and computer labs in the afternoon. It builds upon the contents of the other summer course 'Introduction to multilevel analysis'.
The focus of the first day is on categorical outcome data, in particular binary, ordinal and event history outcomes. It will be shown why linear multilevel models are not appropriate for such data and how multilevel generalized linear models can be used to fit this type of outcome data. Attention will be paid to estimation procedures that are available and how the intraclass correlation coefficients and proportions explained variance are calculated. Special attention is paid to the interpretation of the estimated regression weights in terms of the logits and odds ratios. Analyses will be done in R.
The focus of the second day is on multilevel factor analysis and multilevel structural equation modelling. The interest of such models is generally on theoretical constructs, which are presented by latent factors. It will be shown how to specify factor models at the between- and within-level and how to use fit indices to evaluate model fit. Path models consist of complex paths between latent and/or observed variables, possibly including direct and indirect effects. With multilevel path models, we often have the complication that there are different variables at the individual and group level. R will be used to specify and fit such models.
The focus of day three is on random cross-classifications and statistical power analysis. An example of a random cross-classification is pupils nested within schools and neighbourhoods. In this example a random effect should be included for schools and another one for neighborhoods, and the two may even covary. Such models can be fitted in R and special attention to the interpretation of results will be given. The aim of an a priori statistical power analysis is a calculation of sample size such that an effect can be detected with a sufficient probability. With a two-level model there are two sample sizes: the number of groups and the group size. For some simple experimental designs these sample sizes can be calculated on the basis of mathematical formulae and a demonstration of software will be given. For more complex designs, a simulation study has to be conducted to calculate sample size. It will be shown how to design such a simulation study and how to execute it in R.
Participants are expected to have taken the course Introduction to Multilevel Analysis or a similar course with the same contents (i.e. chapters 1-5 from Hox, Moerbeek and Van de Schoot (2018). Participants are also expected to have experience with analyzing multilevel data in common software such as Mplus, SPSS, R, HLM, or MLwiN. During the computer labs only the R and R studio programs will be used.

The book is not included in fee (about € 45).
Participants are requested to bring their own laptop computer. R and R Studio should be installed on this laptop computer before the start of the course

We also offer tailor-made M&S courses and in-house M&S training. If you want to look at the possibilities, please contact Dr. Laurence Frank at pe.dsai@uu.nl.
Participants will learn to analyze advanced multilevel models and interpret the output and to perform a power analysis.
In the morning there will be lectures while during the afternoons multilevel analyses will be performed in computer practicals. Number of contact hours per day: six. Number of self study hours per day: two to three.
You will receive a certificate upon course completion. Please be aware that this course does not include graded activities, and therefore we cannot provide a transcript of grades.
This course has the following fee options, depending on your status:
Please make sure to include which price is applicable when registering for this course. This information can be added in the “Comment” field during the registration process.
For PhD students from the FSBS at UU:
As a PhD student from the Faculty of Social and Behavioural Sciences (FSBS) at Utrecht University, you can attend up to three Winter or Summer School courses funded by the Graduate School of Social and Behavioural Sciences. Of course, you may choose to take as many other courses as you wish at your own expense, using your personal budget.
When registering, please indicate in the “Comment” field that you are a PhD candidate from the FSBS at UU, so that the course fee can be waived.
There are no scholarships available for this course.
The housing costs do not include a Utrecht Summer School sleeping bag. This is a separate product on the invoice. If you wish to bring your own bedding, please deselect or remove the sleeping bag from your order.
