Kenward-Roger-type adjustment for constructing prediction intervals of network meta-analysis

Description

Kenward-Roger-type adjustment for constructing prediction intervals of network meta-analysis.

Usage

KR(y, S)

Arguments

y	Contrast-based summary data of the outcome measure
S	Covariance estimates of y

Value

Results of the Kenward-Roger-type adjustment for inference of multivariate random-effects model and prediction intervals for network meta-analysis.

• Estimates: Restricted maximum likelihood (REML) estimates, their SE, and Wald-type 95% confidence intervals by the Kenward-Roger-type adjustment.

• Between-studies_SD: Between-studies SD estimate.

• 95%PI: 95% prediction intervals by the Kenward-Roger-type adjustment.
