Loss Function for nested optimization of W and V weights

Description

This is the loss function for the nested optimization of W and V weights used for constructing synthtic control groups according to the methods outlined in Abadie and Gardeazabal (2003) and Abadie, Diamond, Hainmueller (2007) (see references). This function is called by synth automatically, and should not be called manually by a normal user.

Usage

fn.V(variables.v = stop("variables.v missing"), 
X0.scaled = stop("X0.scaled missing"), X1.scaled = stop("X0.scaled missing"), 
Z0 = stop("Z0 missing"), Z1 = stop("Z1 missing"), margin.ipop = 0.0005, sigf.ipop = 5, bound.ipop = 10, ...)

Arguments

variables.v NA
X0.scaled NA
X1.scaled NA
Z0 NA
Z1 NA
margin.ipop NA
sigf.ipop NA
bound.ipop NA
... NA

Details

NA

Value

A list object containing the optimization results.

Note
