Hi everyone,

I have a dataset with dimension of individuals, observations (e.g income, total broadcast time, followers), and repeated observations for individual (e.g. self_esteem, temperament)
Code:
* Example generated by -dataex-. To install: ssc install dataex
clear
input double Income int Broadcast double(Followers CharFC_Rigidity CharFC_AchievementStriving CharC_Conscientiousness PVFC_Hedonism PVFC_UniversalismTolerance Temperament_Choleric Temperament_Sanguine)

end

Since the dataset in wide format with repeated observations for individuals, I want to reshape it into long format so it can be easier to control and regress later on, but after I wrote this:.
Code:
 reshape long CharFC_ CharC_ PVFC_ PVC_ SE_ Role_ Temperament, i(StreamerID) j(Types) string
Code:
* Example generated by -dataex-. To install: ssc install dataex
clear
input float id double Income int Broadcast double(Followers Temperament CharFC_ CharC_)
1 .00411306166423727 104 96751 .                . .
1 .00411306166423727 104 96751 .       .718679414 .
1 .00411306166423727 104 96751 .                . .

1 .00411306166423727 104 96751 .                . .
end
a lots of values went missing, therefore went I try to regress it:
Code:
 reg Income Broadcast Followers Temperament CharFC_ CharC_ Role_
It show error message no observations r(2000)

but, if I try to regress by only put only one of variable from the repeated observations,
Code:
 reg Income Broadcast Followers Role_
it can shows the results.

Nearly the same if I'm using xtreg, fe/re. But this one, variables just went omitted automatically by stata.

Any insight/suggestions/advice for the situation that I have now?

Thank you statalist
