在Elhorst香烟的例子中,做了results=sem_panel_RE(y,[xconstant x],w,T);,出现如下结果:
Pooled model with spatial error autocorrelation and spatial random effects
Dependent Variable = logcit
R-squared = 0.9687
corr-squared = 0.3721
sigma^2 = 0.0016
Nobs,Nvar = 276, 3
log-likelihood = 381.17455

min and max rho = -1.3924, 1.0000

time for eigs = 0.0510
time for t-stats = 0.0180

谁能告诉我,最后两行什么意思?另外,
LR-test significance spatial random effects, degrees of freedom and probability = -254.5794, 1,-11851840087756506000000000000000000000000000000000000000000000000000000000000.0000
这个又作何解释?
