nmaQ: Multivariate Q-statistic and its factorization

In NMA: Network Meta-Analysis Based on Multivariate Meta-Analysis Models

Multivariate Q-statistic and its factorization

Description

Multivariate Q-statistic and its factorized versions (within and between designs) are presented. P-values of the corresponding Q-tests are also presented.

Usage

nmaQ(x)

Arguments

x	Output object of setup

Value

Multivariate Q-statistic and its factorized ones (within and between designs) are presented.

• coding: A table that presents the correspondence between the numerical code and treatment categories (the reference category is coded as 1).

• number of studies: The number of synthesized studies.

• Within designs (individual designs): Q-statistics for individual designs and their P-values.

• Q-statistics: Multivariate Q-statistics and its factorized ones (within and between designs), and their P-values.
