Hello, I am trying to run a model, very similar to the sealions data set example analysis in marked. In that analysis there are 8 strata (A++, A+-, A-+, A–, S++, S+-, S-+, S–), from site A and S, and right tag status + or - and left tag status + or -, which can be unknwon (u). By default, I imagine that the design function assumes that as a convention, the fully known observation (e.g., A++) is specified as reference cell for delta. There is no specification for pi, because all seals are expected to start in site A and tag status ++. How can we define pi if that is not the case for every seal at capture? Some seals may start in A+- (or A-+) and others at N+- (or N-+). Is there a simple way to do that? Many thanks in advance
