Hello playeRs! I'm working on a project for a client. She's modeling hormone levels periodically, and trying to develop a model and fit her data to that model, and subsequently she's trying to cluster individuals based on how well each fits the model. I've been looking at grofit for this, but it doesn't appear that it can do the sort of post-hoc analysis I'm looking for, although it can use a model-free spline fit nicely (reportedly). Does anyone have any packages that can accomplish what I'm looking to accomplish? Thanks in advance for any help you can offer, Wyatt [[alternative HTML version deleted]]
