We discussed this together, There are basically two variants: 1) a geomean(occupancy) and 2) exp(mean(logit(occ))), i.e. geomean(odds). The first option is what @CharlieOuthwaite is using for her PhD "big paper analysis", the latter is what Gary is using for the 2018 pollinator indicator.
Both share a couple of features
@GPowney to document this in the vignette. @CharlieOuthwaite to test option 1 against he own code.
I've added a function into BRCindicators, CompositeTrends. @CharlieOuthwaite can you test this against your code, do you get the same results?!
Just ran the "geometric_raw_occ" version on ants, the indicator values are the same. The CIs are slightly different but I think that might be due to how things have been rescaled as mine start at 100 in year 1.
These methods have been added and documented in TrendSummaries. See here.
Add in @GPowney work on mean estimations using all iterations
