[Abebe Desta]

I am using stata 13 and and regressing xtoprobit for a three round panel. the result gives me that the number of observations just equal to the number of groups. Is there posibility to have same observation and group numbers in a panel data? How can I correct it? . Sigma2_u is also almost zero implying there is no variation over time and I applied oprobit regression as a solution. the result still revealed that the pseudo R-square is very low (below ten percent) and the number of observations I obtained are equal to the number of groups (3143). where I made wrong? I couldnt identify it. Anyone to help me out please?

xtset
panel variable: hh_id (strongly balanced)
time variable: hh_saq13_c, 2004 to 2008, but with gaps
delta: 1 unit


Random-effects ordered probit regression Number of obs = 3143
Group variable: hh_id Number of groups = 3143

Random effects u_i ~ Gaussian Obs per group: min = 1
avg = 1.0
max = 1

Integration method: mvaghermite Integration points = 12

Wald chi2(36) = 813.03
Log pseudolikelihood = -3875.6153 Prob > chi2 = 0.0000
