[R] ED50 from logistic model with interactions

could divide the data and do 3 different logistic regressions, one for each season, but while the Mat50 (i.e. mean Size at 50% maturity) is the same as that calculated by the separate lines regression, Im not sure how this may change the StdErr? Regards, Kate Kate Stark | PhD Candidate

with the observed values. I am also wondering how I might go about calculating confidence (or prediction) intervals around these new fitted values (i.e. fitted new = fitted + autocorrelated error component)? Thanks in advance, Kate == Kate Stark | PhD candidate
