Arguments

nlminb_loops: Integer number of times to call stats::nlminb().
newton_loops: Integer number of Newton steps to do after running stats::nlminb().
eval.max: Maximum number of evaluations of the objective function allowed. Passed to control in stats::nlminb().
iter.max: Maximum number of iterations allowed. Passed to control in stats::nlminb().
getsd: Boolean indicating whether to call TMB::sdreport()
silent: Disable terminal output for inner optimizer?
trace: Parameter values are printed every trace iteration for the outer optimizer. Passed to control in stats::nlminb().
verbose: Output additional messages about model steps during fitting?
profile: Parameters to profile out of the likelihood (this subset will be appended to random with Laplace approximation disabled).
tmb_par: list of parameters for starting values, with shape identical to tinyVAST(...)$internal$parlist
gmrf_parameterization: Parameterization to use for the Gaussian Markov random field, where the default separable constructs a full-rank and separable precision matrix, and the alternative projection constructs a full-rank and IID precision for variables over time, and then projects this using the inverse-cholesky of the precision, where this projection allows for rank-deficient covariance.
estimate_delta0: Estimate a delta model?
getJointPrecision: whether to get the joint precision matrix. Passed to sdreport.
calculate_deviance_explained: whether to calculate proportion of deviance explained. See deviance_explained()
