Thank you. I hope someday I can afford sas. This is the best introduction of quantile regression versus the length of the video.

Unfortunately, we can't post code, or formulas or answer Technical Support questions in this KZbin feedback area. This type of question is best handled by researching in the PROC QUANTREG documentation, working with SAS Tech Support, or, for questions about your own code and data, you can also post your question and a sample of your data in the Community Forums. To open a track with Tech Support, fill out the form at this link: 2.sas.com/6050yFSDp . To post a programming question in the SAS Forums, visit this Forum and post here in the Statistical Procedures forum: 2.sas.com/6051yFSDV. Here's the PROC QUANTREG documentation site: 2.sas.com/6052yFSDn .

Hello, in OLS, we also have heteroscedasticity one of the assumptions to fit in and to correct this problem, we use many techniques like transformation, weightage least-square, etc. in that given case, how quantile regression is different form OLS with corrected heteroscedasticity

The best solution to your earlier question is to send your question to Tech Support with a test program and some test data to illustrate your question. Or, you could post in the Statistical Procedures forum, here: 2.sas.com/6051GqwYS. Hope that helps!

We checked on this, and the standard error is the square root of the sparsity-function estimates of the covariance function matrix. 2.sas.com/605016BIG

Very nice video, I would of liked it better if you discussed interpreting the coefficient estimates as that is a bit tricky for quantile regression.

@Bob Rodriguez, thank you for running us through questions I have here, which I contemplate at times - 1)can coefficients drawn from OLS or Qunatile reg be interpreted in same way? 2) Multi-collinearity has to be taken care through VIF while using quantilereg?

Vijay, this would be an excellent question for either the SAS software communities page on statistical procedures (communities.sas.com/t5/SAS-Statistical-Procedures/bd-p/statistical_procedures ) or for SAS technical support at support.sas.com/en/technical-support/contact-sas.html .

The author of this video uses PROC QUANTREG for quantile regression. For a longer paper on quantile regression by the same author, please refer to this paper: 2.sas.com/60591VPdS . We also have a class on Robust Regression that might be useful to you: 2.sas.com/60511VPdt -- the class covers PROC ROBUSTREG and PROC QUANTREG.
