Scatterplot with logistic regression line -----------------------------------------
scatlog var1 var2 [if exp] [in range] [, ci xb]
Description -----------
scatlog creates a scatterplot of var1 with var2 with a logistic regression line. var1 is assumed to be coded 0/1 and the observed probabilities of var1=1 are plotted at each level of var2. The observed probabilites are computed on a covariate pattern basis (i.e., the number of times var1=1 divided by the number of observations for that covariate pattern).
Options --------
ci plots 95% confidence interval for the conditional predicted probability.
xb plots the logit of var1 and the predicted logits instead of the observed and predicted probabilities.
