In SECFISH: Disaggregate Variable Costs

Description

Function to carry out a constrained regression for a specific fleet segment and a specific type of costs, after setting the metier used by the fleet segment.

Usage

Constrained_regression(COSTS, Fleet_segment, metier,type,path)

Arguments

COSTS	Data frame built applying EA function on individual vessel data and automatically saved as COSTS.csv in the working directory.
Fleet_segment	Fleet segment to be investigated.
metier	Vector of the metier usedd by the specified fleet segment.
type	Type of variable costs on which carry out the constrained regression.
path	Path where the results have to be saved.

Value

COSTS	data.frame: see format in the package (type CO in the console).
Fleet_segment	String defining the fleet segment as reported in the COSTS data frame.
metier	String defining the metier as reported in the COSTS data frame.
type	String defining the type of variable costs as reported in the COSTS data frame.
path	Default path=tempdir()
