In lavaan: Latent Variable Analysis

lavaan samplestats functions

Description

Utility functions related to the sample statistics

Usage

# generate samplestats object from full data
lav_samplestats_from_data(lavdata = NULL, lavoptions = NULL, 
                          WLS.V = NULL, NACOV = NULL)

Arguments

lavdata	A lavdata object.
lavoptions	A named list. The Options lsot from a lavaan object.
WLS.V	A user provided weight matrix.
NACOV	A user provided matrix containing the elements of (N times) the asymptotic variance-covariance matrix of the sample statistics. For a multiple group analysis, a list with an asymptotic variance-covariance matrix for each group.

Examples

# generate syntax for an independence model
HS.model <- ' visual  =~ x1 + x2 + x3
              textual =~ x4 + x5 + x6
              speed   =~ x7 + x8 + x9 '

fit <- cfa(HS.model, data=HolzingerSwineford1939)

# extract data slot and options
lavdata <- fit@Data
lavoptions <- lavInspect(fit, "options")

# generate sample statistics object
sampleStats <- lav_samplestats_from_data(lavdata = lavdata, 
                                         lavoptions = lavoptions)
