Construct reliability summary for composite and latent constructs

Per-construct reliability diagnostics for drm_composite() and drm_latent() constructs in a SEM: alpha (Cronbach's alpha), rho (Raykov's rho / composite reliability), ave (average variance extracted – the mean squared standardized loading), and prop_var (proportion of variance explained).

Usage

reliability(object, ...)

# S3 method for class 'drm_sem'
reliability(object, ...)

Arguments

object

A drm_sem object.

...

Unused.

Value

A drm_reliability data frame: composite, type, method, n_indicators, alpha, rho, ave, prop_var (one row per construct; empty when there are no constructs).

Examples

if (FALSE) { # \dontrun{
sem <- drm_sem(
  fitness = drm_node(drmTMB::bf(fitness ~ body_size), family = stats::gaussian()),
  data = dat,
  composites = drm_composite("body_size", c("len", "mass"), data = dat))
reliability(sem)
} # }
