Re: st: dummy variable for panel cointegration

[varuna dreepaul <varunad1208@gmail.com>]

Thank you for your response. I have used the following commands.
To specify the dummy variable.
Developing countries: 0
Developed countries: 1

. tabulate dummy, generate (dum)

      dummy |      Freq.     Percent        Cum.
------------+-----------------------------------
          0 |        667       50.00       50.00
          1 |        667       50.00      100.00
------------+-----------------------------------
      Total |      1,334      100.00


Then i ran the regression with fixed effect, but the dummies have dropped

Fixed-effects (within) regression               Number of obs      =       950
Group variable: countries                       Number of groups   =        44

R-sq:  within  = 0.4664                         Obs per group: min =         2
       between = 0.8431                                        avg =      21.6
       overall = 0.8786                                        max =        27

                                                F(6,900)           =    131.09
corr(u_i, Xb)  = 0.7548                         Prob > F           =    0.0000
