Kit
Thank you very much. However I have another problem, would you please help?
When I use Random effects linear models with and AR(1) disturbance
estimation, I got:
1. dropped constant
2. rho_ar | -.085 (estimated autocorrelation coefficient)
sigma_u | 0
sigma_e | 348.752509
rho_fov | 0 (fraction of variance due to u_i)
Many thanks.
Ben
