Get model parameters from structural equation models

Description

Returns the coefficients (or posterior samples for blavaan models with summary = FALSE) from a structural equation model.

Usage

## S3 method for class 'blavaan'
get_parameters(x, summary = FALSE, standardize = FALSE, ...)

## S3 method for class 'lavaan'
get_parameters(x, standardize = FALSE, ...)

Arguments

x	A model of class lavaan or blavaan.
summary	Logical. For blavaan models, indicates whether the full posterior samples (summary = FALSE) or point estimates (summary = TRUE) should be returned.
standardize	Logical. Only TRUE returns standardized parameters. Other values, such as 1 or NA, return unstandardized parameters.
...	If standardize = TRUE, a type argument can be used, which is passed to lavaan::standardizedSolution() (or to blavaan::standardizedPosterior() for the posterior samples of blavaan models). For example, type can be "std.all" (the default), "std.lv" or "std.nox". See lavaan::standardizedSolution() for all values. Other arguments are not passed on.

Value

For blavaan models with summary = FALSE, the posterior samples as data frame, with one row per draw (chains pooled) and one column per free or defined parameter. If standardize = TRUE, fixed parameters are included, too. Else, a data frame with the columns Parameter, Estimate and Component.

Examples

m <- lavaan::cfa("visual =~ x1 + x2 + x3", data = lavaan::HolzingerSwineford1939)
get_parameters(m, standardize = TRUE, type = "std.lv")
