Dear Ariful Islam
asdoc follows the Stata official allowed statistic with the sum command. These statistics include :
p1 1st percentile
p5 5th percentile
p10 10th percentile
p25 25th percentile
median median (same as p50)
p50 50th percentile (same as median)
p75 75th percentile
p90 90th percentile
p95 95th percentile
p99 99th percentile
iqr interquartile range = p75 - p25
q equivalent to specifying p25 p50 p75
That means statistics at 80th percentiles are not available. If you need it, you an use asdocx https://fintechprofessor.com/asdocx/, which I shall modify to accept 80th percentile.
