sym.dist.interval: Distance for Symbolic Interval Variables.

Description

This function computes and returns the distance matrix by using the specified distance measure to compute distance between symbolic interval variables.

Usage

sym.dist.interval(
  sym.data,
  gamma = 0.5,
  method = "Minkowski",
  normalize = TRUE,
  SpanNormalize = FALSE,
  q = 1,
  euclidea = TRUE,
  pond = rep(1, length(variables))
)

Value

An object of class 'dist'

Method to use (Gowda.Diday, Ichino, Minkowski, Hausdorff)

normalize

A logical value indicating whether normalize the data in the ichino or hausdorff method.

SpanNormalize

A logical value indicating whether

q

q value for the hausdorff method.
