In xmeta: A Toolbox for Multivariate Meta-Analysis

Trim&fill method for univariate meta analysis

Description

Modified metafor::trimfill.rma.uni to avoid the invalid sqrt in k0 calculation when estimator == "Q0"

Usage

trimfill_rma(
  x,
  side,
  estimator = "L0",
  maxiter = 100,
  method.trim = NULL,
  method.fill = NULL,
  verbose = FALSE,
  ilim
)

Arguments

x	an object of class "rma.uni".
side	the same as in metafor::trimfill
estimator	the same as in metafor::trimfill
maxiter	the same as in metafor::trimfill
method.trim	the model used in rma.uni() for estimating the center when trimming studies, default is x$method
method.fill	the model used in rma.uni() for estimating the center after filling studies, default is x$method
verbose	the same as in metafor::trimfill
ilim	limits for the imputed values as in metafor::trimfill. If unspecified, no limits are used.

Details

It is recommend using fixed-effects for method.trim and random-effects for method.fill when heterogeneity exists.

Value

the same as in metafor::trimfill
