Predict Recruitment

Predict adjusted recruitment by year using DeCesare et al. (2012) methods. If year is FALSE, predictions are made for a 'typical' year. See bb_predict_calf_cow_ratio() for unadjusted recruitment.

bb_predict_recruitment(
  recruitment,
  year = TRUE,
  sex_ratio = 0.5,
  conf_level = 0.95,
  estimate = median,
  sig_fig = 3
)

Arguments

recruitment

An object of class 'bboufit_recruitment' (output of bb_fit_recruitment())

year

sex_ratio

A number between 0 and 1 of the proportion of females at birth.

conf_level

A number between 0 and 1 of the confidence level.

estimate

A function to calculate the estimate.

sig_fig

A whole number of the significant figures to round estimates by.

Value

A tibble of the predicted estimates.
