    The destination does explain that, but the message context on the revision page says "[t]he present address (URL) is a permanent link to this revision, which may differ significantly from the current revision", thus implying that the link is about how the URLs work, and not on currency of replacement content. Thus, it lacks clarity on point ...

  3. Loss function - Wikipedia

    en.wikipedia.org/wiki/Loss_function

    In many applications, objective functions, including loss functions as a particular case, are determined by the problem formulation. In other situations, the decision maker’s preference must be elicited and represented by a scalar-valued function (called also utility function) in a form suitable for optimization — the problem that Ragnar Frisch has highlighted in his Nobel Prize lecture. [4]

    A transcendental entire function is an entire function that is not a polynomial. Just as meromorphic functions can be viewed as a generalization of rational fractions , entire functions can be viewed as a generalization of polynomials.

    An example of a Kaplan–Meier plot for two conditions associated with patient survival. The Kaplan–Meier estimator, [1] [2] also known as the product limit estimator, is a non-parametric statistic used to estimate the survival function from lifetime data.

  8. Not evaluated - Wikipedia

    en.wikipedia.org/wiki/Not_Evaluated

    The categories data deficient and not evaluated (NE) are not on the spectrum, because they indicate species that have not been reviewed enough to assign to a category. [ 4 ] The category of not evaluated does not indicate that a species is not at risk of extinction, but simply that the species has not yet been studied for any risk to be ...

    en.wikipedia.org/wiki/Boolean_algebra

    In mathematics and mathematical logic, Boolean algebra is a branch of algebra.It differs from elementary algebra in two ways. First, the values of the variables are the truth values true and false, usually denoted 1 and 0, whereas in elementary algebra the values of the variables are numbers.
