(2022) in Ecosphere. These\ncan be used to estimate the parameters of a stochastic state\nspace model (i.e. a model where a time series is observed with\nerror). The goal of this package is to estimate the variability\naround a deterministic process, both in terms of observation\nerror - i.e. variability due to imperfect observations that\ndoes not influence system state - and in terms of process noise\n- i.e. stochastic variation in the actual state of the process.\nUnlike classical methods for estimating variability, this\npackage does not necessarily assume that the deterministic\nstate is fixed (i.e. a fixed-point equilibrium), meaning that\nvariability around a dynamic trajectory can be estimated (e.g.\nstochastic fluctuations during predator-prey dynamics).", "License": "GPL-3", "Encoding": "UTF-8", "LazyData": "true", "RoxygenNote": "7.2.3", "Collate": "'bayesfun.R' 'data.R' 'fake_data.R' 'logit_funs.R'\n'particlefilter.R'
