MDFFSS {HDSpatialScan}

MDFFSS scan procedure

Description

This function computes the MDFFSS (Multivariate Distribution-Free Functional scan statistic).

Usage

MDFFSS(
  data,
  MC = 999,
  typeI = 0.05,
  nbCPU = 1,
  variable_names = NULL,
  times = NULL,
  initialization,
  permutations
)

Arguments

data

list of numeric matrices. List of nb_sites (or nb_individuals if the observations are by individuals and not by sites) matrices of the data, the rows correspond to the variables and each column represents an observation time. The times must be the same for each site/individual.

MC

numeric. Number of Monte-Carlo permutations to evaluate the statistical significance of the clusters. By default: 999.

typeI

numeric. The desired type I error. A cluster will be evaluated as significant if its associated p-value is less than typeI. By default 0.05.

nbCPU

numeric. Number of CPU. If nbCPU > 1 parallelization is done. By default: 1.

variable_names

character. Names of the variables. By default NULL.

times

numeric. Times of observation of the data. By default NULL.

initialization

list. Initialization for the scan procedure (see InitScan for more details).

permutations

matrix. Indices of permutations of the data.

Value

An object of class ResScanOutputMultiFunct.
