Hi Statalist members. I?m fairly new to statalist so bear with me and advice me if my question is lacking information or if this is not the right forum for my question. I?m currently writing a thesis in wich I would like to estimate half life of real exchange rates and equilibrium real exchange rates using panel data. I want to estimate the model (y_it ? y_i,t-1) = a_i + b_i * y_i,t-1 + e_it and test if b_1 = b_2 = ? = b This is in effect the Dickey-Fuller transformation commonly used in unit root testing. Can I use the xtrc command to estimate this model and if so will the ?Test of parameter consistency? and z-test on the common coefficient be valid even though the individual t-test are Dickey-Fuller distributed due to the Dickey-Fuller transformation? Also, is the null hypothesis of the ?Test of parameter consistency? b_1 = b_2 =?= b? I cannot find information on this in the help file. My dataset is N=14 and T=205 Regards Anders W.
