Dear All,

I apologise in advance if this is a really basic question, but I am very new to stata.

I am trying to run a regression on panel data (that I have built myself from the British Election Survey) to show the impact of being contacted by a political party, on the way an individual voted in the Brexit Referendum. I have data for April, May and June 2016. I have dummy variables for party contact in April and May (=1 if contacted by a certain party, =0 otherwise) and a dummy variable for the way the individual voted (e.g. =1 if voted Leave, =0 Remain).

I have tried to run xtreg with ,fe r but all my explanatory and control variables are being omitted due to collinearity. I am unable to identify where I am going wrong.

Please let me know if you have any further questions.

Many Thanks.
