jSDMs are currently a Wild West in ecological statistics. Several approaches exist, with very different assumptions and flexibility. For the novice, this field is very difficult to enter. This workshop shall bring together people working with jSDM to provide first-hand experience reports. Thereby participants can relate the presentation better to their own situation, their own questions, and their own data. The ecological interpretation of the model setup will receive particular scrutiny. Some studies have over-interpreted statistical associations as biotic interactions, and we shall facilitate an exchange of ideas between presenters and the audience.
