Known-V meta-analytic random effect: meta_known_V(value, V = V)

Canonical name for the known-sampling-error term in two-stage meta-regression workflows. Formerly meta(value, sampling_var = v) – same engine, new name; the new name makes it explicit that what's "known" is the V matrix (the sampling-error covariance), not some piece of metadata.

Usage

meta_known_V(value, V)

Arguments

value

Response column name (typically the stage-1 BLUP or an effect-size column).

V

Either a column name holding per-row sampling variances (diagonal V) or a length-1 numeric used for every row. For block-diagonal V, build it via block_V() and pass as the known_V = argument to gllvmTMB().

Value

A formula marker; never evaluated.
