Description:
This is the second of a two-part multilevel modeling (MLM) webinar for newbies as well as researchers who have been exposed to it through a prior class or workshop but still have lots of questions. Topics in Part 2 include: 

1. Fixed versus random effects – the difference between fixed and random effects and what changes in the analysis process when random slopes are allowed in the model.

2. Grand-mean versus group centering – what they are and when to use them, unconfounding within and between person effects.

3. Covariance matrices – cover the basics of the residual and random effects covariance matrices.

Description:
This is the first of a two-part multilevel modeling (MLM) webinar for newbies as well as researchers who have been exposed to it through a prior class or workshop but still have lots of questions. Topics in Part 1 include: 

1. Identifying if MLM is necessary – the first step in MLM is figuring out whether data actually violates assumptions of independence.

2. Figuring out the nested structure of your data (including cross-classified models) – Identifying the sources of non-independence in your data, including the possibility of cross-classification.

3. Approaches to dealing with non-independence – when to deal with non-independence through random versus fixed factors.
