POMPOM on CRAN

POMPOM (Person-Oriented Modeling and Perturbation on the Model) is named after my dog pompom, and I made up this acronym for her.

 

The two POM's are two methods, which are structural vector autoregression and impulse response analysis. The hybrid method will allow researchers to conduct in-silico experiments and observe how a dynamical system responds to external perturbations.

 

When applied on psychological systems, POMPOM can provide network-level metrics, which map nicely on psychological concepts, such as emotion regulation efficiency.

 

We have two papers (Yang et al., 2018; 2019) published to provide empirical evidence the network metrics, produced by POMPOM, are linked with mental health outcomes (e.g., depression, anxiety). I am excited for this hybrid method to be applied to more dynamical system models as it provides a realistic and intuitive view of how the system reacts to external perturbation in a coordinated way. 

I would like to know if you tried it out and what surprised you in your findings!
