Hi,
I have 3 waves of panel data. The dv is measured at wave 3. There is one covariate (continuous data) of particular interest that i would like to consider it's impact across all three waves of data. That is, rather than use dummy variables for wave1, wave 2 and wave3 separately i was wondering if it is possible in some way use the data to determine the relationship between the patterns of covariate and the outcome variable. Rather then use something like a cluster analysis (which would profoundly decrease my sample size) is it reasonable for instance to estimate the mean and slope of each subject and model this with respect to the outcome variable. Is it possible to do this within 1 model or would I need to run 2 models.
thanks in advance.
