Hi!
I want to increase the number of observations and for that I like to include more observations of my dependent variable, emission score for 2 more years (2018 and 2019) in my regression model.
I am missing the data of the independent variables for these tweo years, but since the data of my dependent variable are forwarded this should work?
But now I don't know how to adjust my regression command to achieve this? Can anyone give me a hint on this? Thanks a lot!
The regression contains some further variables just put some in for clarification
