Not sure to be honest, as I don’t even understand that line of code. I got it from your suggestion actually, in this post I made a while ago. I’ve been sticking it in every model I’ve been running so that I can compare all the models with Bayes Factors later with performance::compare_performance() and bayestestR::bayesfactor_models()
So far I’ve copied and pasted that one same line into three other models in my RMarkdown file and all of them work fine; its just this 4th, intercept-only model that breaks.
