WebIn your case, your second hypothesis had a p-value of 0.0006 and an FDR of 0.010971585, but the third hypothesis had a larger p-value and a smaller FDR. If you can achieve an FDR of 0.009120248 by setting your p-value threshold to 0.0019, there is never a reason to set a lower threshold just to get a higher FDR. WebThe FDR approach adjusts the p-value for a series of tests.
