generate quantile regression graphs for dummy variable

[Karim Syed]

Hi all

I am trying to generate quantile regression coefficients graph using grqreg command. I run the following commands: (Note: y is my dependent variable, gender, x1, x2, are independent variables. gender is dummy variable which assumes value 1 for female and 0 otherwise.)

qui sqreg y i.gender x1 x2 x3, quantile(.05 .10 .25 .50 .75 .90.95)
grqreg, ols olsci

After I run these commands, I get the following message

1b.gender invalid name
r(198);

Is it that this command does not accommodate the graphs for dummy variables, or I am doing any mistake?
Kindly help

Regards
Karim

grqreg is a user-written program which doesn't support factor variable notation. But as you explain, gender is an indicator in any case, so I doubt that you need the factor variable notation in your sqreg call any way. Re-run without it.
