IRT tool Demo + useR 2009

Posted by Jeroen on March 13, 2009

I've added a little Demo Video to the IRTtool website that shows how the web application can be used for simple IRT analyses. You can watch it on www.irttool.com by clicking the Demo icon.

You can also download the abstract about IRT tool that was submitted to the useR 2009 Committee.

Stage Line Diagram Article Online available.

This week my very first publication, in cooperation with Stef van Buuren, became available online. The article about Stage Line Diagrams, for which the Puberty Plot webapplication was made, can be downloaded from the Early View section of the Statistics in Medicine website.

Feel free to play around with the web application. It's public and does not require installation of any software.

New multilevel-video page

Posted by Jeroen on March 6, 2009

I made a new webpage for the multilevel instruction video's. It uses a css video-box to display the video's. Currently only video's for the first example from the book of Hox (2009) are on the page, but more will follow soon.

By the way, if you do not like the fancy-pants webpage, you can also access the video's directly from the video directory.

Welcome!

Thanks for visiting my website. It does not contain too much information yet, the main reason being that I am still a student and have not (yet) accomplished a lot. However, in the mean time you can read something about me and check out projects I am currently working on. Please feel free to drop me an email if you have any questions/comments.
