Abstract:
|
The Center for Statistical Consultation and Research at the University of Michigan (CSCAR) has many off-campus clients. We have implemented a flexible remote consulting model using CENTRA software, allowing us to consult on statistical and data-base management issues for clients located anywhere with an internet connection. Fitting Linear Mixed Models (LMMs) for longitudinal or clustered data presents unique challenges in a remote setting. Having a "hands-on" connection with a client allows the consultant to work with data, provide guidance in model setup, interpret results, and work with diagnostics. The client can see and use different statistical packages on the consultant's desktop. Notes may be kept on the client's computer to document the session. Problems with LMM model convergence may be more readily diagnosed in a remote consulting session than via email or over the phone.
