[statnet_help] Node Entry and Exit in STERGM

Hello All,

I am new to SNA and I am looking to model a co-authorship network. I have determined that STERGM is a good method to use here, but I am wondering if it is possible to account for nodes entering and exiting the network over the course of the model. I am not trying to model/predict entry or exit, only to account for it as it is known in my dataset in order to prevent the model trying to account for a lack of edges from times when a node was not present.

I have gone through the tutorial on TERGMs here (https://statnet.org/workshop-tergm/tergm_tutorial.html) which says it is possible to do node entry and exit, but when I look at the documentation in the relevant packages, I have been unable to find anything more about it.

Does anyone know if this is possible, and if so, have any examples of it being done, pointers to how this would be done in the code, or places I should look in the documentation?

Thanks,
Willow
