permutationPA | R Documentation |
Estimate a number of significant principal components from a permutation test.
permutationPA(dat, B = 100, threshold = 0.05, verbose = TRUE)
dat |
a data matrix with |
B |
a number (a positive integer) of resampling iterations. |
threshold |
a numeric value between 0 and 1 to threshold p-values. |
verbose |
a logical indicator as to whether to print the progress. |
Adopted from sva::num.sv
, and based on Buja and Eyuboglu (1992)
permutationPA
returns
r |
an estimated number of significant principal components based on thresholding p-values at |
p |
a list of p-values for significance of principal components |
