Hi, thank you very much for referring me to this post, but I am not sure it would apply to my case as I am not creating any sequences for my regression?
my dataframe "finaldata" looks as follows:
YVAR CONTROL1 XVAR INSTRUMENT
1 NA 6 0 0
2 0 5 NA NA
3 0 5 0 0
4 1 6 NA NA
5 NA 4 0 0
6 0 6 52 23
7 1 6 0 1
8 0 4 31 3
9 0 4 43 98
10 1 3 0 0
The variables XVAR and YVAR have a lot of 0 values and NA but over half are positive values.
Any suggestions would be really appreciated!
Thank you very much
