qtest: Cochran Q Test of Heterogeneity
In mixmeta: An Extended Mixed-Effects Framework for Meta-Analysis

Description Usage Arguments Details Value Author(s) References See Also

This is a generic function to perform a Cochran Q test of (residual) heterogeneity. The function invokes particular methods which depend on the class of the first argument. Currently, specific methods exist for several meta-analytical models in various packages: qtest.mixmeta, qtest.mvmeta, and qtest.dosresmeta.

1	qtest(object, ...)

`object`	an object for which the test is desired
`...`	further arguments passed to specific methods.

The test assesses the null hypothesis that the variability in the distribution of the outcomes is explained only in terms of within-unit estimation errors. This corresponds to a test on the hypotesis that there is no variation attributable to random-effects terms.

Returned values depend on the specific class. Usually, the results of the test.
