simulate_congeneric: Simulate observations from a congeneric one-factor model.

In alphaci: Confidence Intervals for Coefficient Alpha and Standardized Alpha

Simulate observations from a congeneric one-factor model.

Description

Simulate observations from a one-factor model with specified latent variable and error variable distributions. The error terms are not correlated, hence the model is congeneric.

Usage

simulate_congeneric(
  n,
  k,
  sigma = 1,
  lambda = 1,
  latent = stats::rnorm,
  error = stats::rnorm
)

Arguments

n	Number of observations.
k	Size of matrix or number of testlets.
sigma	Vector of error standard deviations. Repeated to have k elements.
lambda	Vector of factor loadings. Repeated to have k elements.
latent	Distribution of the latent variable.
error	Distribution of the error variable.

Value

Covariance matrix.
