Hi everyone!

I am using a five quarter longitudinal study (labour force survey UK data) for a panel data fixed effects model. I am finding it a bit difficult to define the time variable (without which the data cannot be declared as panel data) for the dataset as I am not sure of what exactly it is. The dataset is unbalanced and there is no time variable as such, only the week in which the responder was surveyed. Any suggestions on just how to go about defining the dataset would be very helpful.
