Query Regarding - Error (RDD - Regression Discontinuity Design - bwselect(mserd))

[Ammar Hussain]

Hi, all Respected Researchers:

I am running the following command to find the optimal bandwidths under RDD - Regression Discontinuity Design:

rdbwselect LL_ADAC1 PRless2_1, kernel(uniform) c(0) p(1) bwselect(mserd)

after running this command get this error in STATA:

bwselect() incorrectly specified
r(7);

Please tells the solution of this error, while I think I run the command in correct way.
