How to calculate Z-score using Dtrios' output? #7

Closed silvewheat closed 4 years ago

silvewheat commented 4 years ago

Hello Milan,

As most published papers using Z-score (>3 or >2) to determine which trio is significant, I wonder if I can get the Z-score from the output file of Dtrios? Is the "combine_stderr.txt" contains all the D-statistics calculated using Jackknife block under the arrangement that same with "combine.txt"? So, can I use these data to calculate Z-score?

Hi silvewheat

Dtrios and DtriosCombine output the p-values for each trio. If you prefer the Zscores you can calculate them from the p-values. For example in R: Zscore <- qnorm(pValue, lower.tail=F)
