hi there, so i have a panel regression of 174 nations and their GDP growth for every year 1994-2017, i am trying to regress using a fixed effect model this growth against 20 dummy variables, each dummy variable coincides with 1 of 20 world regions, therefore each nation will have only have one dummy for which their number is 1, i am trying to see the effect of being in each region on GDP growth over the period, however when I regress this using the standard xtreg fe format it omits one of my regions (in this case Pacific island nations) and uses that as the intercept for which to assess all my other regions, is there any way to stop this from happening?
