standardized.coefficients: Standardized Coefficients for 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)

std.coef(...)

Arguments

object

an object of class sem returned by the sem function.

digits

number of digits for printed output.

...

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.
