Number of gaps in sample:  468
(note: the number of observations per panel, e(n_sigma) = 1,
       used to compute the disturbance of covariance matrix e(Sigma)
       is less than half of the average number of observations per panel,
       e(n_avg) = 4.8360656; you may want to consider the pairwise option)

Linear regression, correlated panels corrected standard errors (PCSEs)

Group variable:   number                        Number of obs      =       590
Time variable:    year                          Number of groups   =       122
Panels:           correlated (unbalanced)       Obs per group: min =         1
Autocorrelation:  no autocorrelation                           avg =  4.836066
Sigma computed by casewise selection                           max =         5
Estimated covariances      =      7503          R-squared          =    0.5879
Estimated autocorrelations =         0          Wald chi2(5)       =    105.64
Estimated coefficients     =        17          Prob > chi2        =    0.0000
