I’m getting the following error when I run my model (below): " Argument ‘autocor’ should be specified within the ‘formula’ argument." I looked this up, but it looks like the autocor argument was replaced with car, and I do have a car argument in the formula. I’m wondering if this is somehow related to the mo(DaysSinceLastExposed) and the prior(dirichlet(), class = “simo”, coef = “moDaysSinceLastExposed1”) aspect of the model because the error is present when I added in these aspects. Any idea what is wrong with the model here? I’m guessing it’s some syntax thing.
Thank you for your help!
