Value

A data.frame containing standardised model parameters.

Arguments

object

An object of class INLAvaan.

type

If "std.lv", the standardized estimates are on the variances of the (continuous) latent variables only. If "std.all", the standardized estimates are based on both the variances of both (continuous) observed and latent variables. If "std.nox", the standardized estimates are based on both the variances of both (continuous) observed and latent variables, but not the variances of exogenous covariates.

se

Logical. If TRUE, standard errors for the standardized parameters will be computed, together with a z-statistic and a p-value.

ci

If TRUE, simple symmetric confidence intervals are added to the output

level

The confidence level required.

postmedian

Logical; if TRUE, include posterior median in estimates.

postmode

Logical; if TRUE, include posterior mode in estimates.

cov.std

Logical. If TRUE, the (residual) observed covariances are scaled by the square root of the `Theta' diagonal elements, and the (residual) latent covariances are scaled by the square root of the `Psi' diagonal elements. If FALSE, the (residual) observed covariances are scaled by the square root of the diagonal elements of the observed model-implied covariance matrix (Sigma), and the (residual) latent covariances are scaled by the square root of diagonal elements of the model-implied covariance matrix of the latent variables.

remove.eq

Logical. If TRUE, filter the output by removing all rows containing equality constraints, if any.

remove.ineq

Logical. If TRUE, filter the output by removing all rows containing inequality constraints, if any.

remove.def

Logical. If TRUE, filter the ouitput by removing all rows containing parameter definitions, if any.

nsamp

The number of samples to draw from the approximate posterior distribution for the calculation of standardised estimates.
