Distances

 

Between the samples in the data set for interval type of the data

 

 

Intercluster distances

the average distance between all of the samples belonging to two different clusters

where  and  - number of samples included in the clusters  and  respectively

the distance between the centres of two clusters

where ,

the distance between the most remote samples belonging to two different clusters

the closest distance between two samples belonging to two different clusters

the distance between the centre of a cluster and all of samples belonging to a different cluster

the maximal distance from samples of one cluster to the nearest sample of another cluster

,

where

 

 

Intracluster distances

the distance represents the distance between the most remote samples belonging to the same cluster

the distance defines the average distance between all of the samples belonging to the same cluster

 the distance reflects the double average distance between all of the samples and the cluster’s centre
