Calculates the concentration set threshold. The concentration set is the subset of the p-values that contains all discoveries at confidence level 1-alpha.

concentration (hommel, alpha=0.05)
|
hommel |
The hommel object for the complete multiple testing problem. |
alpha |
The type I error allowed. |
Returns a p-value. P-values larger than that value contain no discoveries in this data set at this level of alpha and may be disregarded.
