No prior knowledge of Mplus is required.

Software and Materials

For this hands-on workshop we will be working with Mplus. For those who are not working with any specific software, we provide all syntax and output for each example to allow for participation without the use of any software.

If you do not own a copy of Mplus, a free but limited demonstration version is available for download at the Mplus Website. To run all of the examples used during the workshop, it is recommended that participants have a licensed copy of the Mplus Base program with the Combination Add-On.

Handout materials and datasets will be provided.

Coffee/tea and light snacks will be provided at each break. Lunch will not be provided however, there are plenty of restaurants in the area.
