In fAssets: Rmetrics - Analysing and Modelling Financial Assets

Distance Measures

Description

Allows to measure the distance or similarity between assets.

Usage

assetsDist(x, method="cor", ...)

corDist(x)  
kendallDist(x) 
spearmanDist(x) 
  
mutinfoDist(x, nbin=10)
         
euclideanDist(x)    
maximumDist(x)      
manhattanDist(x)  
canberraDist(x)   
binaryDist(x)      
minkowskiDist(x) 
         
braycurtisDist(x)   
mahalanobisDist(x) 
jaccardDist(x)     
sorensenDist(x) 

Arguments

x	any rectangular time series object which can be converted by the function dist() into a distance object.
method	a character string, the method from which to compute the distances. Allowed methods include cor, kendall, spearman, mutinfo, euclidean, maximum, manhattan, canberra, binary, minkowski, braycurtis, mahalanobis, jaccard, difference, or sorensen.
nbin	an integer value, the number of bins, by default 10.
...	optional argument to be passed the distance function.

Details

corDist, kendallDist, and spearmanDist call the base cov function from R.

mutinfoDist calls the function mutinfo from the contributed R package bioDist.

euclideanDist, maximumDist, manhattanDist, canberraDist, binaryDist, and minkowskiDist are functions build on top of R's base package.

braycurtisDist, mahalanobisDist, jaccardDist, and sorensenDist call functions from the contributed R package ecodist.

Value

an object of class dist.
