Estimate_DEPMWt_biomass.RdCombined DEPM parameters to calculate spawning biomass, total number of females and the number of females per weight class using the DEPMwt approach
Estimate_DEPMWt_biomass(adult.pars, adult.vars, weight.pars.vars)
| adult.pars | The output of `combine_estimates`. This included each of the DEPM parameters estimated using this package. These can be grouped by Timestep/Region and will be used to estimate results for each combination of these.Multiple egg mortalities will produce multiple annual results. |
|---|---|
| adult.vars | The output of `combine_variances`. This included each of the DEPM parameters estimated using this package. These can be grouped by Timestep/Region and will be used to estimate results for each combination of these. Multiple egg mortalities will produce multiple annual results. |
| weight.pars.vars | A dataframe that must include the columns: "Wt_bin", "Prop", "Prop_var", "Wt", "Fecundity", "Fec_var". These correspond to weight bin number (must start at 1), proportion of females in each weight bin, the multinomial variance of the proportion of females in each weight bin, weight of each weight bin, fecundity-at-weight of that weight bin and the variance of fecundity-at-weight for that weight bin, respectively. Wt, fecundity and Fec_var can be calculated using the `Estimate_batch_fecundity` function. These can be grouped by Timestep/Region and will be used to estimate results for each combination of these |
A list of results for spawning biomass, total number of females and the number of females per weight class. These list elements will be grouped by Timestep/Region if these were provided with the parameters. The standard deviations of these estimates are also returned
