Thanks everyone for your commenst. Thanks for your patience and I have now made the codes available . YOu can find them here. www.mihiretukebede.com/posts/2023-03-30-quantile-regression/
Overall effects of categorical variables I am doing quantile regression in R ; the dependent variable is a count variable and I have categorical predictors. Some of the categorical variables with 4 levels, in the parameter estimates table I get results for the 3 levels of the categorical variable compared to the level I have set as the reference. How to get the overall effects of categorical variables for quantile regression model. In multiple linear regression it is possible to get the overall effect by function “anova(model)”. When I perform the same function with a quantile regression model did not give same output.
If I understand correctly, you would like to see the annova table for your quantile regression model. In quantreg package, there is anova.rq() function. Please check that. I hope I answered your Q. rdrr.io/cran/quantreg/man/anova.rq.html
I keep getting the "Error in rq.fit.br(wx, wy, tau = tau, ...) : Singular design matrix" error with the same program. Tried with two different datasets but the error persists, any idea what might be causing it or how to rectify it?
but what If I want to check which factors out of many provided say in a dataset affect the 60th quantile the most at let say 95 confidence level plus visualising it ?
Really useful information and well explained. Perhaps some of the length of the video could be cut down by a little more editing. It's quite daunting to have to spend 40 minutes on the topic when most of the core information takes you much less to explain. Really well done otherwise! Thank you!
Thank you very much for your great feedback. You're right, it would have been done in a much shorter time. But, I was thinking of people with little experience in R.
@@r_pydatascience that's true it is helpful for to see each step in that case. Maybe two separate types of videos would solve the issue. Of course, that's a lot to ask for! Either way good job!

Thank you so much Sir for this informative video

Thanks a lot for this very informative and detailed video. Keep on going! :) Regards, Joachim
I am so glad to have this feedback from you, Joachim. Thank you very much. I have also learned a lot from your videos and blogs.
@@r_pydatascience That's great to hear, thanks for the kind words! :)

really nice video, Where can we find this data and R code? Can you please share it with us? We want to do a practicle. Thanks

If you saved your taus as
taus
Thanks man this video is very helpful. Can you please share your codes. It will be very helpful for me. Thank you.
