Talk:Triple correlation

Notation
Currently the article starts out with


 * The triple correlation of an ordinary function on the real line is the integral of the product of that function with two independently shifted copies of itself:



\int_{-\infty}^{\infty} f^{*}(x) f(x+s_1) f(x+s_2) dx.

$$

From the wording, I don’t see why there is an asterisk on the first function. If it is there for a reason, it should be defined and its presence explained (and otherwise it should be deleted). Loraof (talk) 20:59, 12 December 2017 (UTC)
