kantorovich_CVX: Computes Kantorovich distance with CVX

Description

Kantorovich distance using the CVXR package

Usage

kantorovich_CVX(
  mu,
  nu,
  dist = NULL,
  solution = FALSE,
  stop_if_fail = TRUE,
  solver = "ECOS",
  ...
)

Arguments

mu

(row margins) probability measure in numeric mode

nu

(column margins) probability measure in numeric mode

dist

matrix, the distance to be minimized on average; if NULL, the 0-1 distance is used.

solution

logical; if TRUE the solution is returned in the "solution" attributes of the output

stop_if_fail

logical; if TRUE, an error is returned in the case when no solution is found; if FALSE, the output of psolve is returned with a warning

solver

the CVX solver, passed to psolve

...

other arguments passed to psolve

Examples

mu <- c(1/7,2/7,4/7)
nu <- c(1/4,1/4,1/2)
kantorovich_CVX(mu, nu)
