pfunc: The p_delta(eta) function.

In metagen: Inference in Meta Analysis and Meta Regression

Description

Returns the p-function.

Usage

  pfunc(y, d, x)

Arguments

y	study responses.
d	heteroscedasticity.
x	design matrix.

Value

A vector valued function.

Examples

bcg   <- bcgVaccineData()
bcg_y <- bcg$logrisk
bcg_d <- bcg$sdiv
bcg_x <- cbind(1,bcg$x)
pfunc(y=bcg_y, d=bcg_d, x=bcg_x)

# Calculating the Mandel-Paule estimate:
pfunc(y=bcg_y, d=bcg_d, x=bcg_x)(dim(bcg_x)[1] - dim(bcg_x)[2])

Example output

function (etavec) 
{
    return(sapply(etavec, pfuncuno))
}
<environment: 0x75a16b0>
[1] 0.1421259
