Dear all,
need your big help on this. I have a data set like this as attached:
Each of my subject has more than 1 visit and i'm trying to find out how their global score change over time with each visit hence i'm doing a GEE analysis, adjusting for the other variables in the attached image.
Eventually, i'm supposed to tabulate my data in this format
Year 1 2 3 4 5 6 7
Model 1 xx yy zz aa bb cc dd p value
Model 2
Help needed on the coding needed to do this in R
