lavaan samplestats functions

lav_samplestats.Rd

Utility functions related to the sample statistics

Usage

# generate samplestats object from full data
lav_samp_from_data(lavdata = NULL, lavoptions = NULL, 
                          wls_v = NULL, nacov = NULL)

Arguments

lavdata

A lavdata object.

lavoptions

A named list. The Options slot 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_samp_from_data(lavdata = lavdata, 
                                         lavoptions = lavoptions)
