MplusWizard is a place where you get to learn magical SEM skills that will empower you to reveal intricate patterns in real life. It was created to offer a very gentle introduction into SEM, in an intuitive and non-mathematical way. It will help you become a wizard!

This set of online courses emulates the courses I deliver in Cambridge. You can request a certificate at the end. So they really are meant to be taken as a “course”, not simply a “resource bank”.
How does it work? Watch this 5-minute video.

Note: The video below suggests you will get the materials in “weekly installments” , over 2-3 weeks. However, in response to a wave of requests, the courses will now be delivered as fast-track training (similarly to the courses I teach in Cambridge) and the duration will be only 5 days for each course. And you will receive all videos and files at the start of the course. If you need a slower pace due personal circumstances, contact me and we will make it work for you.


In addition to the Foundation course (Wizard’s Cat), there are 3 Specialised courses:

  • Multilevel (Magic School).
  • Multiple group (Potion Master).
  • Longitudinal (Spell Caster).

Also in response to requests, you can now take the courses on any dates you wish, so long as you start the course on a Monday. The Wizard’s Cat, Potion Master and Magic school courses last 1 week, from Monday to Friday. The Spell Caster course is 2 weeks long (on workdays). For all courses, you will have access to the videos for a further 4 weeks after the end of the course. And you will be able to access the contents 24/7 (even though the parameters of the course are just weekdays).


What is it actually like?

Here is a video of a full SEM. The way to use the videos is to “work through them”, not just “watch” them. You will receive the actual files, so you can annotate them and create a bank of annotated models. These will provide a useful way to quickly remember all the details later. In fact, these will probably be more useful as a quick reference than the actual videos, as they provide more efficient searching of specific bits and bobs. And by annotating files as you watch the videos, you will efficiently internalise the new knowledge. Enjoy!

catIn addition, I also offer “The Wizard’s Cat”, my own favourite course. It is a foundation course and includes:

  • An introduction to SEM and Mplus
  • Path analysis with mediation effects
  • Different types of regression models
  • An introduction to factor analysis
  • Examples of EFA and CFA
  • Examples of a full SEM


This course is aimed at absolute beginners who have no technical background. And if you are an absolute beginner, this foundation course is a pre-requisite for all other courses.

Dates & Prices


My name is Gabriela Roman. I am a Research Associate at the Institute of Criminology, University of Cambridge, where my main research interest is the development of cognitive and emotional self-regulation and the role of self-regulation for behaviour difficulties (in early childhood) and criminal behaviour (in adolescence and early adulthood). I am particularly interested in the contributions of other actors to the development of a person’s self-regulation. Over the years, I have also been involved in various international projects as a consultant. I am currently working on a book about young people’s pathways into crime, from age 13 to age 24. Previously I was fortunate to learn a little bit about various branches of psychology and criminology via a PhD in developmental psychology (Cambridge University), an MPhil in criminological research (Cambridge University), and a BA in cognitive and social psychology (Jacobs University Bremen).

Courses: I have been delivering training courses since 2013. My flagship courses are in-person and take place in Cambridge. They are hosted by Selwyn College, which looks like a fairy tale. We complete our experience with 3 coffee & cake breaks, as well as lunch in the Great Hall (which also includes cake, of course):


Webinars: I also developed the Mplus Webinarium, a platform through which I sometimes deliver highly interactive webinar series. This format was created with an aim to bring all the interactive and immersive features you would expect from an in-person course directly to the comfort of your living room:


Mathematics: I also co-developed a course in mathematics based on the “STEP I” exam that used to form the basis for admissions to a variety of Maths BSc courses (originating at Cambridge University). This course is aimed at broadening highschool leavers’ access to deep mathematics, so that every pupil who wishes to delve deeper into foundational mathematics is able to so regardless of their circumstance:


About Mplus Wizard

Mplus Wizard is my latest project. It aims to further increase flexibility by allowing you to learn at your own pace (e.g. by allowing you to pause/rewind videos) and your own schedule, while retaining the support you would get when studying in my presence (e.g. via the option to post questions online on the web dashboard directly to me). I record and edit the videos undergoing a minutious process to maximise their quality and delivery in the hope that they provide an enjoyable and fulfilling experience for you.

If you have any questions then please feel free to contact me using the contact details at the bottom of the page.

All the best,
