使用普通的命令,比如logit y x1 x2 x3会给出伪R方的值
Logistic regression Number of obs = 2539
LR chi2(11) = 400.45
Prob > chi2 = 0.0000
Log likelihood = -962.59785 Pseudo R2 = 0.1722
但是使用svy命令,比如svy: logit y x1 x2 x3就没有R方的值了,为什么?怎么才会给出R方数值?
Survey: Logistic regression
Number of strata = 14 Number of obs = 2539
Number of PSUs = 48 Population size = 367156415
Design df = 34
F( 11, 24) = 193.44
Prob > F = 0.0000
