qtest.dosresmeta {dosresmeta} | R Documentation |
This method function performs a Cochran Q test of (residual) heterogeneity on fitted dose-response meta-analytical models
represented in objects of class "doseremeta
". It is implemented only for a two-stage approach and will return NULL
otherwise.

In (multivariate) dose-response meta-analytical models, the test assesses the null hypothesis that the variability in the
(multivariate) distribution of the outcomes is explained only in terms of estimation error in each study, measured by the within-study (co)variance matrices
stored in the component Slist
of dosresmeta
objects. This is equal to test the hypothesis that the between-study (co)variance matrix is
a zero matrix, and there is no random deviation in study-specific estimates.
