st: CDF Differences

Dear Statalisters,
Mine is a rather simple question. I have plotted the "cumulative
distribution function" (CDF) for one variable (KNOWLEDGEINDEX) depending on
whether the dummy variable RADIO takes value 0 or 1. I have used the
following commands:
cdf KNOWLEDGEINDEX, normal by (RADIO)
or alternatively,
cdfplot KNOWLEDGEINDEX, by(RADIO) norm nocdf
Now, I would like to plot the differences in the CDF of KNOWLEDGEINDEX by
RADIO with the pointwise confidence bands. In one sentence, I would like to
have a graph with the KNOWLEDGEINDEX in the horizontal axis and the CDF
Difference in the vertical axis.
Thank you in advance for the assistance,
Regards,
Francesco.
