Errata:
The desired case for the Lack of Cohesion in Methods is in fact LCOM* = 0 (read: no lack of cohesion) occurs if every method accesses every attribute and the undesired case is LCOM* = 1 (read: a high lack of cohesion) occurs if each attribute is only accessed by only one method.
It is fixed in the slides download.
