Horn's parallel analysis – suggested number of factors.

Delegates to psych::fa.parallel() when available; otherwise compares observed eigenvalues to the 95th percentile of random-data eigenvalues.

Usage

morie_psymet_parallel(data, nsim = 100, seed = 42)

Arguments

data

Numeric matrix or data.frame of items.

nsim

Integer; number of simulated random datasets (default 100).

seed

Integer; RNG seed for reproducibility.
