The data contains anonymized survival information for boreal caribou population 'C', with years 2010-2013 represented as single placeholder rows with all-NA measurement columns. These placeholder rows signal unobserved years to the model: the data pipeline uses them to set Annual factor levels, then strips them before building the likelihood. Random effects for unobserved years are estimated purely from the hierarchical prior. The dataset follows the methodology described in DeCesare et al. (2012) for estimating population growth rates using adult female survival data.
