When you start Mathematica, Correlation is undefined and is just a generic
function.  You need to open a standard package that defines it before
referencing it.  Use the Master Index to determine which standard package(s)
define a function.

<< I have been experiencing some weird output. Some functions just output the
input. No errors, no indications of a problem. Most functions work well, but
some just don't provide any feedback as to the error.

For example:
xlist = {1, 2, 3, 4, 5};
ylist = {2, 4, 6, 8, 10};
Correlation[xlist, ylist]

Yields the output with no error:

Correlation[{1, 2, 3, 4, 5}, {2, 4, 6, 8, 10}]
