Hello,

I have split up my independent variable of interest into quantiles where the first quantile has the lowest values and the 5th one has the highest values of the independent variable.
I made regressions and included these quantiles using the code i.quantiles.
However, when I do this, it omits the first quantile in the regression. This is the quantile with the lowest values. This was good for most of my analyses, but now my independent variable is temperature, where I would actually prefer to have the medium quantile be omitted.

How can I omit the medium dummy variable (quantile 3)?

Thanks,
Masa
