log likelihood function =   0.10994988E+03

LR test of the one-sided error =   0.16044958E+03
with number of restrictions = 3
[note that this statistic has a mixed chi-square distribution]

number of iterations =     17

(maximum number of iterations set at :   100)

number of cross-sections =     31

number of time periods =      5

total number of observations =    155

thus there are:      0  obsns not in the panel
