Extract Parameters from Lavaan Models

Description

This function extracts parameters (loadings, variances, etc.) from a lavaan model. P-values are formatted appropriately (e.g., <0.001 for very small values).

Usage

extract_latent_parameters(
  model,
  type = "loadings",
  standardized = FALSE,
  digits = 3,
  ...
)

Arguments

model	A fitted lavaan model.
type	Type of parameters to extract: "loadings", "variances", or "all". Default is "loadings".
standardized	Logical; if TRUE, returns standardized estimates. Default is FALSE.
digits	Number of decimal places for p-value formatting (default=3)
...	Additional arguments passed to lavaan::parameterEstimates or lavaan::standardizedSolution.

Value

A data frame containing the extracted parameters with formatted p-values.

Examples

library(lavaan)
model <- 'F1 =~ x1 + x2 + x3'
fit <- cfa(model, data = HolzingerSwineford1939)
extract_latent_parameters(fit, type = "loadings")
