Extract path coefficients

Description

Extracts (standardized) path coefficients from a psem object.

Usage

coefs(modelList, standardize = "scale", standardize.type = "latent.linear",
  intercepts = FALSE)

Arguments

modelList

A list of structural equations.

standardize

The type of standardization: none, scale, range. Default is scale.

standardize.type

The type of standardized for non-Gaussian responses: latent.linear, Menard.OE. Default is latent.linear.

intercepts

Whether intercepts should be included in the coefficients table. Default is FALSE.

Details

P-values for models constructed using lme4 are obtained using the Kenward-Roger approximation of the denominator degrees of freedom as implemented in the pbkrtest package.

Different forms of standardization can be implemented using the standardize argument:

For binary response models (i.e., binomial responses), standardized coefficients are obtained in one of two ways:

Value

Returns a data.frame of coefficients, their standard errors, degrees of freedom, and significance tests.
