標題[問題] 請問為什麼stata沒有出現常數項
時間Tue Apr 15 05:49:27 2008
我跑panel logit
指定我用xtlogit y x1 x2 x3 x4 x5, fe
就只有出現概似比對數值......常數項怎麼沒有出現@@
Iteration 0: log likelihood = -716.16888
Iteration 1: log likelihood = -671.93661
Iteration 2: log likelihood = -671.14011
Iteration 3: log likelihood = -671.13833
Conditional fixed-effects logistic regression Number of obs = 1792
Group variable (i): id Number of groups = 256
Obs per group: min = 7
avg = 7.0
max = 7
LR chi2(5) = 99.89
Log likelihood = -671.13833 Prob > chi2 = 0.0000
