Initialization from an ordering vector

Initialization from an ordering vector

make_init(
  X,
  ordering_vec,
  K,
  assume_EEI = TRUE,
  nugget = 0,
  discretization = c("equal", "quantile", "kmeans"),
  na_action = c("drop", "error")
)

Arguments

X

numeric matrix (n x d).

ordering_vec

numeric vector of length n (can contain NA).

K

number of mixture components.

assume_EEI

logical; if TRUE, use shared diagonal covariance (EEI-like).

nugget

nonnegative scalar added to diagonal variances/covariances.

discretization

one of "equal", "quantile", "kmeans".

na_action

how to handle NA in ordering_vec: "drop" or "error".

Value

list(pi, mu, sigma, keep_idx, cluster_rank)
