Prepares the data matrix X and the dependence structures U and Sigma for clustering and testing. If Sigma is not provided, it is estimated using an i.i.d. sample Y of the same variables, with an associated dependence structure UY. Sample splitting can be used to generate Y from X when observations are independent. Checks are performed to ensure the compatibility of the dimensions of the data and dependence structures, and to verify the positive-definiteness of U and Sigma.

Usage

setup.model(
  X,
  U = NULL,
  Sigma = NULL,
  Y = NULL,
  UY = NULL,
  precUY = NULL,
  sample_split = FALSE,
  nY = NULL
)

Arguments

X

Data matrix of size \(n \times p\) containing the observations and variables to be clustered and tested.

U

Optional \(n \times n\) positive-definite matrix representing the dependence structure among observations in X. If not provided, observations are considered independent with unit variance.

Sigma

Optional \(p \times p\) positive-definite matrix representing the dependence structure among variables in X. If not provided, it is estimated using Y and UY.

Y

Optional \(n_Y \times p\) data matrix containing an i.i.d. sample of the same variables as in X, used to estimate Sigma when it is not provided. If not provided and sample_split = TRUE, Y is generated by sample splitting from X.

UY

Optional \(n_Y \times n_Y\) positive-definite matrix representing the dependence structure among observations in Y. If not provided, observations in Y are considered independent with unit variance.

precUY

Optional \(n_Y \times n_Y\) positive-definite matrix representing the inverse of UY. If UY is provided but precUY is not, precUY is computed as the inverse of UY. If neither UY nor precUY is provided, observations in Y are considered independent with unit variance.

sample_split

Logical indicating whether to generate Y by sample splitting from X when Sigma is not provided. If TRUE, Y is generated by randomly splitting the observations in X into two disjoint sets, one for clustering and testing, and the other for estimating Sigma. If FALSE, an i.i.d. sample Y must be provided to estimate Sigma.

nY

Optional integer specifying the number of observations in Y when sample_split = TRUE. If not provided, it defaults to half of the sample size of X.

Value

A list containing the following elements:

X

Data matrix of size \(n \times p\) containing the observations and variables to be clustered and tested. If sample_split = TRUE, X contains only the observations used for clustering and testing after sample splitting.

U

\(n \times n\) positive-definite matrix representing the dependence structure among observations in X. If not provided, it is set to the identity matrix.

Sigma

\(p \times p\) positive-definite matrix representing the dependence structure among variables in X. If not provided, it is estimated using Y and UY.
