chiCombP {methylPipe} | R Documentation |
Fisher's method implementation, used to combine the results from several independent tests bearing upon the same overall hypothesis.
chiCombP(Pvalues)
Pvalues |
an array of pvalues |
Pvalues will not be corrected for multiple testing. The sum of the log of the pvalues is determined (S). -2*S has a chi-square distribution with 2k degrees of freedom, where k is the number of tests being combined. A chi-square test is then performed.
The chi-square final pvalue
