st: Trouble Producing a Regression Discontinuity Graph with a Specified Bandwidth
Date

I am using the rd command
(http://ideas.repec.org/c/boc/bocode/s456888.html) in Stata/MP 13.0,
Windows. I am only able to obtain a discontinuity graph if I do not
specify a bandwidth. In other words, once I use both the ‘graph’ and
‘bw’ options, I receive an ‘invalid syntax’ error message. I wonder if
anyone else is having this problem, or sees the error in my code? Thank
you for your consideration, Dara Shifrer

Three variables specified; jump in treatment
at Z=0 will be estimated. Local Wald Estimate
is the ratio of jump in outcome to jump in treatment.
Assignment variable Z is tv10cgim
Treatment variable X_T is tb10a2m
