Arguments

leave_out

Unit to omit from the dataset. For single-level models this is a row index. For multilevel models this is one highest-level cluster value.

data

Data used for analysis.

studyID

Character string representing the study ID.

effectID

Character string representing the effect size ID.

sample_size

Character string representing the sample size of the studies.

effectsize_type

Type of effect size being analyzed.

formula

The formula used for specifying the fixed and random structure.

variable_names

Vector of character strings representing the attributes with correlations. The attributes that are correlated should be separated by an underscore.

effectsize_name

Character string representing the name of the effect size column in the data.

estimation_method

Type of estimation used, either "REML" or "MLE".

variance

Character string representing the variance column name.

varcov_type

Type of variance covariance matrix computed.

weights

User specified matrix of weights for analysis.

structure

Between studies covariance structure.

intercept

Whether a model intercept should be specified.

missing

Whether missing data should be removed, or kept.

optim_method

Optimization method passed to optim().

robustID

A character vector specifying the cluster group to use for robust standard errors.

multivariate_covs

A one-sided formula for multivariate analysis covariates.

lasso

TRUE/FALSE indicator that specifies if LASSO results are returned.

lasso_args

A list of LASSO specific arguments.

tol

Tolerance of the optimization.
