Rank Sum Tests
m struggeling with some statistics given by the vcf file: the Ranksumtests. I started googleing arround, but that turned out to be not helpfult for understanding it (in may case). I really have no idea how to interprete the vcf-statistic-values comming from ranksumtest. I have no clue whether a negative, positive or value near zero is good/bad. Therefore im asking for some help here. Maybe someone knows a good tutorial-page or can give me a hint to better understand the values of MQRankSum, ReadPosRankSum and BaseQRankSum. I have the same problem with the FisherStrand statistics. Many, many thanks in advance.
