I'm using quantreg rq() to perform quantile regression on a large data set.
Each record has 4 fields and there are about 18 million records in total. I
wonder if anyone has tried rq() on a large dataset and how long I should
expect it to finish. Or it is simply too large and I should subsample the
data. I would like to have an idea before I start to run and wait forever.
In addition, I will appreciate if anyone could give me an idea how long it
takes for rq() to run approximately for certain dataset size.
