Draw the connectivity matrix (Cij) according to the dataset presented above.
Remember that the elements of this matrix are related to the distances between
points following the next criteria:
If d $; 2 c=O
If d > 2 c=l

4.2 Calculate the Moran's I coefficient. Please write by hand all your intermediate
calculations (only the result of MC is not valid and will not be marked). Notice that the
values for the measurements linked to Points 1, 2, and 3 will correspond to the last
three digits of your student number (A, B, C) (6 marks).
