dist.Symbolic: Calculates distance between interval-valued symbolic data

Description

Calculates distance between interval-valued symbolic data for four distance types

Usage

dist.Symbolic(data,type="U_2",gamma=0.5,power=2)

Arguments

data

symbolic data

type

type of distance used for symbolic interval-valued data

U_2 - Ichino and Yaguchi distance

M - distance between points given by means of intervals (for interval-values variables),

H - Hausdorff distance,

S - sum of distances between all corresponding vertices of hyperrectangles given by symbolic objects with interval-valued variables

gamma

parameter for calculating Ichino and Yaguchi distance

power

parameter for calculating distance: Ichino and Yaguchi distance, Hausdorff distance
