Calculating linkage

Let us revisit the example with three players on a field. The distance matrix between these three players is shown below and is available as the variable dist_players.

From this we can tell that the first group that forms is between players 1 & 2, since they are the closest to one another with a Euclidean distance value of 11.

Now you want to apply the three linkage methods you have learned to determine what the distance of this group is to player 3.

2 11
3 16 18

  • Calculate the distance from player 3 to the group of players 1 & 2 using the following three linkage methods.
    • Complete: the resulting distance is based on the maximum.
    • Single: the resulting distance is based on the minimum.
    • Average: the resulting distance is based on the average.
