log likelihood function =   0.17995525E+03

LR test of the one-sided error =   0.29575714E+03
with number of restrictions = 3
[note that this statistic has a mixed chi-square distribution]

number of iterations =     15

(maximum number of iterations set at :   100)

number of cross-sections =     29

number of time periods =      5

total number of observations =    145

thus there are:      0  obsns not in the panel
