fn.V {Synth} | R Documentation |
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.
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, ...)
