Hello,

I have a matched 1:20 dataset of 4 hour telemetry steps that I am analyzing in Stata using clogit.  I am clustering on individual animal to produce robust SEs.  However, I want to look at the autocorrelation structure of the data and have never done this before.  I am using only non-collinear variables in my model.
  
1. How do I explore autocorrelation and partial autocorrelation of model residuals with matched data.   
2. I assume I can use the Durbin Watson test for temporal autocorrelation but is this a straight call after clogit or do I need to reformat the dataset specifically for time series?  Right now I have a generic hour and generic date in my work. 

Thank you for any links to places I can explore further.

Best,

Cheryl
