How to get a column to return percentile

[#1]

Hi everyone,

I am working to get P50, P90 and P95 data into a data set based on an array of numbers .

I know that I can run a distribution and it will show the values but I am trying to do this for too many files to make it feasible.

Is there a formula or other way to get a column that returns with the values I am looking for based on a specific delimiter such as batch? I am currently using JMP 15.0 and any help would be appreciated.

Have you tried with Summary platform?

Optionally you can use Col Quantile() function in a formula and Summarize() function if scripting

Frankly I was tunnel-visioned enough that I did not think of using the summary table. I also utilized the formula for col quantile to make all of them.

Thank you!

The Quantile() function will give you what you want if you are looking to calculate your percentiles for an array of data.

names default to here(1);

A = [1.2, 1.5, 10, 25, 31, 40, 50, 99, 1000, 5000, 25000, 100000];

P50 = Quantile( .5, A );

This can also be used against a column of data in a data table if you reference the data table as a matrix of data

names default to here(1);

dt = open("$SAMPLE_DATA/Big Class.jmp");

P75 = Quantile( .75, dt[0,4]);
