Example output from the `opt_mbp()` function, finding the optimal mbp for each group and desired convergence threshold.
ex_opt## `ex_opt` A data frame with 1 rows and 5 columns:
Generally a strain, run, and species of fish (e.g. Nimbus Fall Chinook = Fall-run Chinook Salmon from Nimbus Hatchery)
The minimum rSSR value
The maximum rSSR value
the rSSR value which represents the `thresh_level` cutoff for estimating convergence
The desired convergence level (100-x)
The identified optimum mbp for the given threshold and group
