Binscatter and Confidence Interval

[Jose Ignacio Torrealba]

Is any way you can add Confidence Interval in this code? So you can see it in the graph.

binscatter cotiza_pension TT, line(connect) xline(0)

Thanks!

From a glance at the help, the answer is no. binscatter (from SSC, as you are asked to explain: FAQ Advice #12) is I think intended only to be descriptive and exploratory, which to me is positive in aim Its attraction is perhaps greatest for some of its more unusual options, not so much its defaults as shown here.

Your example doesn't convince as one where confidence intervals would be useful or interesting, however. I would reach here for a local polynomial as an exploratory smooth. My eye picks out a slight decline in outcome with the predictor how much of a big deal that is and how much variability there is around the changing level are different questions.

Dear Jose Ignacio,

There is a command, presented in last year's Stata Economics Virtual Symposium, that I believe does what you want. It is in line with Nick's intuition. The command's name is -binsreg-. You can find more information here:

Also, for anyone interested, this is the program of this year's virtual symposium.
