Hi all Assume I have a data set xx;
Group: 1=group1 , 2=group2 IQ: 1= High, 0 =low fit <- glm(IQ ~group, data = xx, family = binomial()) summary(fit) Results Estimate Std. Error z value Pr(>|z|) (Intercept) -2.55456 0.210 -12.273 < 5e-16 *** group 0.36180 0.076 3.952 5.24e-05 *** the odd ratio = exp(0.36180 )= 1.435912 My question is that the log-odd estimate 0.3618 is it for group1 or group2? What does the odd ratio 1.43359 is interpreted?
