votep {metap}R Documentation

Combine p-values by the vote counting method

Description

Combine \(p\)-values by the vote counting method

Usage

votep(p, alpha = 0.5)
## S3 method for class 'votep'
print(x, ...)

Arguments

p

A vector of significance values

alpha

A value defining the significance value limits, see Details

x

An object of class ‘votep

...

Other arguments to be passed through

Details

By default splits the \(p\)-values at 0.5 with those below counting as positive and those above counting as negative. However setting alpha allows specifying a neutral zone. In that case values between alpha and 1 - alpha will be assumed to be neutral and only those outside the zone counted as positive or negative. If the value of alpha is greater than unity it is assumed to be a percentage.

The values of \(p_i\) should be such that \(0 < p_i < 1\) and a warning is given if that is not true. A warning is given if, possibly as a result of removing illegal values, fewer than two values remain and the return values are set to NA.

The plot method for class ‘metap’ calls plotp on the valid p-values.

Value

An object of class ‘votep’ and ‘votep’, a list with entries

p

\(p\) value

pos

Number of positives

neg

Number of negatives

alpha

The cut–off significance value lying in the range 0 to 1

validp

The input vector with illegal values removed
