Does groupyr.LogisticSGL support multiclass classification and if yes how to interpret coef_?

[JohannesWiesner]

Hi! First of all, thanks for this wonderful package! I have a dataset with three subject groups and wonder if I can use groupyr.LogisticSGL in this case. I couldn't find any documentation if groupyr.LogisticSGL only supports binary classification. It runs through, so I guess multiclass classification is supported? And if yes, how would I interpret the (n_features,) coef_ attribute? Is groupyr.LogisticSGL implicitly running a one-vs-rest classification in the background?
