Thank you so much!!!!!!!
Thanks a lot!
using this command, it's possible to control for some covariates that are not continuous (dummy or categorical)?
Thank you! Your video was very helpful :)
if I want to plot the best fit using the explanatory variable and y, then in the same graph I want to plot the fitted line with a fixed effect. how can I do it.
Thank you so much, but it's like you've talked about lots of commands such that I lost track of how to group variables as the title of the video suggests. But am grateful for the piece of knowledge you've added to me. Cheers tutor.

Hello 272. Thank you for your tutorial on this important command. I have a question though. You executed the command on the total sample. how do you modify this code if, for example, your sample was stratified by year and you wanted to estimate the percentile marriage rates by year.
Thank you for your help. With regards from Dolcy and Mercy.

I had never seen bar graphs used to represent means of continuous variables like this. Would a box-plot be more suitable in this case?

Thanks very much for your tutorial. Please I am just learning STATA, and I need assistance. So I have 2 separate variable as Systolic and Diastolic. I am now trying to write a condition where STATA can return "normal" for me where the systolic is <=140, and "Abnormal" where it is >140, and then "missing" in places with missing values *for the Systolic g SysBldPressure = cond(inrange(Systolic,140,.), "Abnormal","Normal"). The challenge with this code is that it returns missing values as normal also.
for some reason when I am doing the same thing, the number of observation in each quantile is not the same. Can anyone tell why?? and what should I do now
Thanks! Great and fast fix.
