What's the difference between correlation and linkage?

Correlation


Definition:

  • (n.) Reciprocal relation; corresponding similarity or parallelism of relation or law; capacity of being converted into, or of giving place to, one another, under certain conditions; as, the correlation of forces, or of zymotic diseases.

Linkage


Definition:

  • (n.) The act of linking; the state of being linked; also, a system of links.
  • (n.) Manner of linking or of being linked; -- said of the union of atoms or radicals in the molecule.
  • (n.) A system of straight lines or bars, fastened together by joints, and having certain of their points fixed in a plane. It is used to describe straight lines and curves in the plane.

Example Sentences:
