[R] GEE for a timeseries of count (one cluster)

Hi! I was wondering if there were any packages that would allow me to fit a GEE to a single timeseries of counts so that I could account for autocorrelation in the data. I tried gee, geepack and yags packages, but I do not get standard errors for the parameters when using a single cluster. Any

[R] zero standard errors with geeglm in geepack

Hi! I am using geeglm to fit a Poisson model to a timeseries of count data as follows. Since there are no clusters I use 73 values of 1 for the ids. The problem I have is that I am getting standard errors of zero for the parameters. What am I doing wrong? Thanks, Michelle > N_Base [1] 95 8
