  • Each sub-folder contains a mplus_out folder storing Mplus files with results and corresponding syntax.
    • These files include the results obtained from Mplus (.out files) and allow table and figure reproduction without a Mplus license.
  • Script prefixes:
    • F_: Writes out Mplus syntax and fits the model using Mplus (requires Mplus license).
    • R_: Reads the .out Mplus files containing the results.
    • FR_: Writes syntax and reads .out Mplus files containing results; typically used for models fitted without Mplus (e.g., OLS models in the appendix).
