standardized.coefficients: Standardized Coefficients for Structural Equation Models

In sem1: Structural Equation Models

Description

These functions calculate standardized regression coefficients for structural equation models. The function std.coef is simply an abbreviation for standardized.coefficients.

Usage

standardized.coefficients(object, digits = 5, oneheaded=TRUE, twoheaded=TRUE)

std.coef(...)

Arguments

object	an object of class sem returned by the sem function.
digits	number of digits for printed output.
oneheaded	standardize path coefficients? Default is TRUE.
twoheaded	standardize variances and covariances? Default is TRUE.
...	arguments to pass to standardized.coefficients.

Value

Returns a data frame with the standardized coefficients, labelled both by parameter names and by arrows in the path diagram for the model.
