    This course is for learners with a foundational knowledge of regression analysis. Prior SPSS experience is helpful, but not required. Mplus experience is not required.

  • There is no way that I will be able to set aside the four days required to take this course. Is the timing flexible?

    We understand completely! The timing is entirely up to you. Once you enroll and the course has launched, you will have unlimited access to the content. You are free to pause and return to your lessons as needed.

  • Will you give me feedback on my analyses?

    Dr. Geiser is happy to answer questions related to course content and Quantfish promptly resolves any technical issues related to the course platform. If you are interested in personal consultation on your own data, please contact us to get started.
