In stremo: Functions to help the process of learning structural equation modelling

Description

Raw data and model syntaxes for the paper by Laughlin (2011) determinants of nitrification potential in a pine forest.

Usage

  data(laughlin)
  laughlin
  laughlin.model

Format

A data frame with 82 observations on 11 variables and one character vector with the syntax for the final model.

Note

The final model is represented by figure 3. The model converges and we get the same standardized parameters and degrees of freedom. We get a slightly higher p-value for the robust maximum likelihood chi-square than reported. Data were transformed following instructions the supplementary material (Table S1).
