  • Discrepancy between qreg table output and grqreg graphs

    Dear All,

    For my master thesis, I am applying quantile regression and came across an issue I am struggling to solve.

    I am currently using the qreg command for my estimations. Ideally, I wanted to use bootstrapped SEs (with the command bsqreg), however, this does not allow me to apply sample weights while qreg does.
    To graph the results, I use grqreg but the command seems to use other standard errors as the qreg estimation, even though I run them together (the coefficient of a variable is significantly different from zero for some quantiles in the graph but not in the qreg estimations).

    Thus, I have the following questions:
    • Do you have an idea where the discrepancy between the graph and quantile regression table output could stem from and how I could try to solve the issue?
    • Do you know whether I could somehow apply sample weights when using quantile regression with bootstrapped standard errors (bsqreg)?
    Thanks a lot already in advance!

    Best,

    Valentina
