Hi,
I am able to generate easily the median of a variable for a given year, e.g.
sort year
by year: egen medianprice = median(price)
Does anyone know how I can generate the 30th and 70th percentile of a
variable? I know I can use the centile function to display the 30th and 70th
percentiles, and the centile function can definitely be used with "by", but
it can't be used with "egen" it seems.
Thanks
Yvonne
