percentile formula

Dear community,

Please state the percetnile formula being used in JMP tabulate function. I know this is not the same as the formula in excel because they are giving me different result.

I need it badly to justify the JMP application in our system.

Thanks

Re: percentile formula

JMP quantiles seem to give the same results as the Excel percentile.exc function (found in newer Excel versions). Functions percentile.inc and the (depreciated) percentile can yield different results from JMP.

If you use tabulate you may need to "set format" to display all decimal numbers of the interpolated result.
