This function returns the identity and number of rejected hypotheses for several multiple testing procedures and different nominal Type I error rates.
1 | mt.reject(adjp, alpha)
|
adjp |
A matrix of adjusted p-values, with rows
corresponding to hypotheses and columns to multiple testing
procedures. This matrix could be obtained from the function
|
alpha |
A vector of nominal Type I error rates. |
A list with components
r |
A matrix containing the number of rejected hypotheses for several multiple testing procedures and different nominal Type I error rates. Rows correspond to Type I error rates and columns to multiple testing procedures. |
which |
A matrix of indicators for the rejection of individual hypotheses by different multiple testing procedures for a nominal Type I error rate |
