fitMeasures: Fit Measures for a Latent Variable Model

Description

This function computes a variety of fit measures to assess the global fit of a latent variable model.

Usage

fitMeasures(object, fit.measures = "all", baseline.model = NULL, 
            output = "vector", ...)
fitmeasures(object, fit.measures = "all", baseline.model = NULL, 
            output = "vector", ...)

Arguments

object

An object of class '>lavaan.

fit.measures

If "all", all fit measures available will be returned. If only a single or a few fit measures are specified by name, only those are computed and returned.

baseline.model

If not NULL, an object of class '>lavaan, representing a user-specified baseline model. If a baseline model is provided, all fit indices relying on a baseline model (eg. CFI or TLI) will use the test statistics from this user-specified baseline model, instead of the default baseline model.

output

Character. If "vector" (the default), display the output as a named (lavaan-formatted) vector. If "matrix", display the output as a 1-column matrix. If "text", display the output using subsections and verbose descriptions. The latter is used in the summary output.

...

Further arguments passed to or from other methods. Not currently used for lavaan objects.

Value

A named numeric vector of fit measures.

Examples

# NOT RUN {
HS.model <- ' visual  =~ x1 + x2 + x3
              textual =~ x4 + x5 + x6
              speed   =~ x7 + x8 + x9 '

fit <- cfa(HS.model, data=HolzingerSwineford1939)
fitMeasures(fit)
fitMeasures(fit, "cfi")
fitMeasures(fit, c("chisq", "df", "pvalue", "cfi", "rmsea"))
# }
