Maximum entropy reconstruction of stock distribution and inference of stock density from line-transect acoustic survey data
distribution from acoustic line-transect data. MaxEnt is founded on the bedrock of probability theory and ... allows the most efficient possible use of known data in the inference process. The method takes explicit ... account of spatial correlation in the observed data and seeks to reconstruct a distribution of density ... across the whole survey area that is both consistent with the observed data and for which the entropy is ...
