Solves min ||Xq - y||^2 s.t. q >= 0 for each species, spatially
deconvolving catch into per-cell CPUE estimates. More statistically
rigorous than the weighted method but requires an overdetermined system
(rule of thumb: at least 3x more trips than H3 cells).
Arguments
- trips
Combined effort + catch tibble from
join_effort_catch().- top_n
Integer. Number of top species to model.
- min_trips
Integer. Minimum unique trips per H3 cell to retain.
