log likelihood function = 0.86717534E+01
LR test of the one-sided error = 0.64637817E+01
with number of restrictions = 4
[note that this statistic has a mixed chi-square distribution]
number of iterations = 11
(maximum number of iterations set at : 100)
number of cross-sections = 10
number of time periods = 1
total number of observations = 10
thus there are: 0 obsns not in the panel
