Description

Function for running a retrospective analysis

Usage

run_retro(fit, folds, progress = TRUE)

Arguments

fit	Object from fit_model()
folds	Number of years to 'fold' back
progress	Display progress bar? (Generated using the progressr and progress packages)

Details

This function runs a retrospective analysis whereby terminal survey index estimates are excluded from the analysis. A hindcast is also preformed in each fold where observed values are left out but predicted to measure the models forecasting skill.

Value

Returns a list with three objects:

1. retro_fits - a list including a series of fits from each retrospective fold

2. hindcasts - a data.frame with observed, but left out, and predicted indices from each fold

3. mse - mean squared error of the hindcasts (measure of forecasting skill)
