A note on the cluster variation method

Kikuchi's cluster variation method (CVM) is reformulated as the truncation of a Möbius inversion. An attempt is made to explicate and simplify the various approaches to the CVM. This formulation makes apparent the connection of the method with other types of cluster approximation. An illustration of the procedure is provided.
