When using asdocx summarize, I find that I cannot report for 90th percentile observation.
sysuse auto, replace
asdocx sum price, stat(N p99)
asdocx sum price, stat(p90)
Error in the stat( p90 ) option!
only the following statistics are allowed
N sd mean semean median count sum range min max var cv skewness
kurtosis iqr p1 p5 p10 p25 p50 p75 p95 p99 tstat
I see that p90 is not in the statistics list, but it’s a bit counterintuitive that p10 is available while p90 is not.
