Non parametric estimation of Regression Discontinuity analysis in Stata(rdrobust)

[Beson Dong]

I use the following code for non parametric estimation:

rdrobust y v,c(0) kernel(uni) bwselect(mserd) all

But the results kept showing:

rdrobust() not able to compute the loc.poly.bandwidth (h)above the threshold. Please run rdbwselect() for more information}

Please help if anybody have any idea how to do so.Thanks！

Hi Beson,
I think the next step here is to see if you have enough information above and below the threshold to actually analyze the data using the regression discontinuity design.
Perhaps if you do a simple

kdensity v,

It may show you if you have enough variation above and below zero, to estimate your model.

while Fernando gives valuable advice, why not run the rdbwselect program itself? if should have been installed at the same time you installed rdrobust from the Stata Journal; type
