Plot Quantile Regression

[OLMABA JALA]

Hello,

I would like to conduct a quantile regression and plot the regression afterwards.
I am getting an error message 1b.incomegroupinvalid name
Do you know what I am doing wrong?

I am trying to do this with the following commands:

 qreg birthrate i.incomegroup

grqreg, ci ols olsci

Hi Olmaba
The problem is that -grqreg- does not work with factor variables. So it doesn't understand why you are using "i.incomegroup".
You can do two things:
1. create the dummies yourself and add it to the regression.
2. try the command qregplot (from ssc)
