Getting Started

For a brief entry point, open the MATLAB Live Script:

open docs/GettingStarted.mlx

The GettingStarted.mlx file provides a brief entry point for setting up the toolbox and locating the example scripts. The example scripts themselves provide step-by-step instructions for running simulations and summarizing results.

Typical Workflow

A typical workflow in TestSEM Pro is:

1. Initiate the three main inputs for the simulation study: DGP, Estimators, and SimulationOption.
   • Specify the type of data-generating process (DGP).
   • Specify the basic information about the DGP and the names of the estimators.
2. Enter detailed information for the three inputs.
   • Specify the true parameter values for the DGP.
   • Enter the estimation methods and their corresponding input arguments in Estimators.
   • Specify the simulation options in SimulationOption.
3. Run the simulation study.
4. Summarize and save the results.
