Hi,   The following code would fx. result in af normalised value of 1.8414202783 for original values of 1,000,000.   proc rank data=input_csv normal=BLOM out=output_ranks; var DEBT_EBITDA_rec; ranks rank1; run;   However when calculating the normalised values manually (used in different setup) I end up with a value of 1.734508.   In SAS my proces would be something like:   #Calculate simple ranks with TIES=MEAN -> results in a rank of 2,885 for the value 1,000,000 proc rank data=input_csv out=simpleRankTest; var DEBT_EBITDA_REC; ranks rank1;   #Total non-negative observations are 3,009, meaning that I should be able to use the formula (from SAS documentation): probit(2,885-(3/8)/3,009-(1/4)) = probit(0.95..) = 1.7345.. run;   What do I not see?
