rcurves_Millar

Predict gillnet selectivity (old Millar method)

A compilation of fish stock assessment methods for the
analysis of length-frequency data in the context of data-poor
fisheries. Includes methods and examples included in the FAO
Manual by P. Sparre and S.C. Venema (1998), "Introduction to tropical fish
stock assessment" (<https://www.fao.org/documents/card/en/c/9bb12a06-2f05-5dcb-a6ca-2d6dd3080f65/>),
as well as other more recent methods.
