In SpaCCr: Spatial Convex Clustering

Description

Solve Spatial Convex Clustering problem for path of regularization parameters in parallel

Usage

SpaCC_Path_Parallel(X, w, gamma.seq, nu = 1/nrow(X), verbose = FALSE,
  tol.base = 1e-04, tol.miss = 1e-04, max.iter.base = 5000,
  max.iter.miss = 500, ncores = 2)

Arguments

X	A subject (n) by variable (p) matrix; the data
w	A vector of length p-1; weights for clustering
gamma.seq	A vector of positive scalars; regularization parameter sequence
nu	A positive scalar; augmented Lagrangian paramter
verbose	Logical; should messages be printed?
tol.base	A small positive scalar; convergence tolerance for base SpaCC problem.
tol.miss	A small positive scalar; convergence tolerance for missing data problem.
max.iter.base	A positive integer; maximum number of iterations for base SpaCC problem
max.iter.miss	A positive integer; maximum number of iterations for missing data problem
ncores	A positive integer; number of cores to use

Value

A list with elements UPath, VPath, LamPath, and gamma.seq
