Q-test to assess compatibility between original and replication effect estimate

Computes p-value from meta-analytic Q-test to assess compatibility between original and replication effect estimate.

Qtest(thetao, thetar, seo, ser)

Arguments

thetao: Numeric vector of effect estimates from original studies.
thetar: Numeric vector of effect estimates from replication studies.
seo: Numeric vector of standard errors of the original effect estimates.
ser: Numeric vector of standard errors of the replication effect estimates.

Value

p-value from Q-test.

Details

This function computes the p-value from a meta-analytic Q-test assessing compatibility between original and replication effect estimate. Rejecting compatibility when the p-value is smaller than alpha is equivalent with rejecting compatibility based on a (1 - alpha) prediction interval.
