# Master thesis

Currently, Heleen is working on her master thesis for the program Methodology and Statistics for the Behavioural, Biomedical and Social Sciences. The title of the thesis is *Multilevel Multivariate Imputation by Chained Equations through Bayesian Additive Regression Trees* and is supervised by Thom Volker, Hanne Oberman and Gerko Vink from Utrecht University. It is expected to be finished in May 2024.

For now, you can find the research report for this thesis project and associated LateX file here.

# Reproducible Research Project

For the course *Markup languages and Reproducible Research* Heleen created a reproducible research project. You can download a local copy of the repository here. This Github repository contains the file that is fully reproducible when running the script and is licensed.

# R-package

Again, for the course *Markup languages and Reproducible Research* Heleen created simple R-package which is availabele on Github. The package is called `datageneration`

and can be installed using the following code: `devtools::install_github("heleenbrueggen/datageneration")`

The package includes versioning, a license, tests, and a reference with DOI that can be found in the Github repository.

The package generates a simple data set containing normally distributed variables with a specified mean and standard deviation. From those variables a dependent variables `y`

is created assuming a linear relationship between the variables. The user can specify the number of variables, the mean and standard deviation of the variables, and the amount of observations.
