Hello. i have a question which is when i run the regression of granger i got error message that there is repeated time. of course my obs are 34000 and the time around 2009to 2017. then i removed the duplicated id obs ( which means one obs per firm) my sample became only 1908 then i tried to do it again but i got same error message. how can i do granger causality test ?
please
