ecostate: State-Space Mass-Balance Model for Marine Ecosystems

Fits a state-space mass-balance model for marine ecosystems, which implements dynamics derived from 'Ecopath with Ecosim' <https://ecopath.org/> while fitting to time-series of fishery catch, biomass indices, age-composition samples, and weight-at-age data. Package 'ecostate' fits biological parameters (e.g., equilibrium mass) and measurement parameters (e.g., catchability coefficients) jointly with residual variation in process errors, and can include Bayesian priors for parameters.
