inspectSampleCov: Observed Variable Correlation Matrix from a Model and Data

In lavaan: Latent Variable Analysis

Observed Variable Correlation Matrix from a Model and Data

Description

The lavaan model syntax describes a latent variable model. Often, the user wants to see the covariance matrix generated by their model for diagnostic purposes. However, their data may have far more columns of information than what is contained in their model.

Usage

inspectSampleCov(model, data, ...)

Arguments

model	The model that will be fit by lavaan.
data	The data frame being used to fit the model.
...	Other arguments to sem for how to deal with multiple groups, missing values, etc.

Details

One must supply both a model, coded with proper model.syntax and a data frame from which a covariance matrix will be calculated. This function essentially calls sem, but doesn't fit the model, then uses lavInspect to get the sample covariance matrix and meanstructure.
