combine {SCMA}

Statistical combination of p-values

Description

Calculates a general p-value by statistically combining the p-values of a number of independent studies, to determine whether a general significant result is obtained.

Usage

combine(method, pvalues = read.table(file.choose(new = FALSE)))

Arguments

method

Indicates which combining function should be used: "x" (multiplicative) or "+" (additive)

pvalues

File in which the p-values can be found. Default: a window pops up in which the appropriate file can be selected.

Details

When using the default 'pvalues' argument, a window will pop up to ask in what file the pvalues can be found. This text file containing the pvalues should consist of 1 column with all the obtained pvalues.
