influence.rlmerMod: Per-observation influence on (\hat{beta}, \hat{sigma},...

In robustlmm: Robust Linear Mixed Effects Models

Per-observation influence on (\hat{\beta}, \hat{\sigma}, \hat{\theta}) for an rlmerMod fit.

Description

Thin wrapper that returns the stacked influence matrix used by cooks.distance. Cheaper to call this once and pass the result back to cooks.distance via IF = . than to recompute the numerical Jacobian twice.

Usage

## S3 method for class 'rlmerMod'
influence(model, do.coef = TRUE, ...)

Arguments

model	An rlmerMod object.
do.coef	Ignored (kept for compatibility with the influence generic).
...	Currently unused.

Value

A list with IF_beta (p \times n), IF_sigma (1 \times n), IF_theta (L \times n), and the full implicitIF_full object as full.
