INFERENCE Subcommand (META CONTINUOUS command)

The META CONTINUOUS command calls the meta-analysis procedure with continuous outcomes and raw effect size data. The optional INFERENCE subcommand specifies the estimation methods.

MODEL
The optional keyword specifies the model type. When /TRIMFILL is specified, this keyword also controls the model that is used by pooling in the trim-and-fill analysis. When /BIAS is specified, this keyword also controls the model that is used by the regression-based test.
RANDOM
The default setting that builds the random-effects model.
FIXED
Assumes the fixed-effects model.
ESTIMATE
The optional keyword specifies the estimator. The process is available when MODEL = RANDOM, and is otherwise ignored. When /TRIMFILL is specified, this keyword also controls the estimator that is used by pooling in the trim-and-fill analysis. When /BIAS is specified, this keyword also controls the estimator that is used by the regression-based test.
REML
The default setting that applies the iterative method and calculates the restricted maximum likelihood estimator.
ML
Applies the iterative method and calculate the maximum likelihood estimator.
BAYES
Applies the iterative method and calculate the empirical Bayes estimator.
HEDGES
Applies the non-iterative method and calculates the Hedges estimator.
HUNTER_SCHMIDT
Applies the non-iterative method and calculates the Hunter-Schmidt estimator.
DERSIMONIAN_LAIRD
Applies the non-iterative method and calculates the DerSimonian-Laird estimator.
SIDIK_JONKMAN
Applies the non-iterative method and calculates the Sidik-Jonkman estimator.
ADJUSTSE
The optional keyword controls whether to apply the Knapp-Hartung standard error adjustment. The process is available when MODEL = RANDOM, and is otherwise ignored. When /TRIMFILL is specified, this keyword also controls the standard error adjustment that is used by pooling in the trim-and-fill analysis. When /BIAS is specified, this keyword also controls the standard error adjustment that is used by the regression-based test.
NONE
The default setting that does not apply the adjustment.
KNAPP_HARTUNG
Applies the adjustment method.
TRUNCATED_KNAPP_HARTUNG
Applies the adjustment method and truncates the value if less than 1 when estimating the variance-covariance matrix.
