  2. Multicollinearity - Wikipedia

    en.wikipedia.org/wiki/Multicollinearity

    Working with polynomial terms (e.g. , ), including interaction terms (i.e., ) can cause multicollinearity. This is especially true when the variable in question has a limited range. This is especially true when the variable in question has a limited range.

  3. Collinearity - Wikipedia

    en.wikipedia.org/wiki/Collinearity

    In geometry, collinearity of a set of points is the property of their lying on a single line. [1] A set of points with this property is said to be collinear (sometimes spelled as colinear [2]). In greater generality, the term has been used for aligned objects, that is, things being "in a line" or "in a row".

    A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula.

    A Koch snowflake has an infinitely repeating self-similarity when it is magnified. Standard (trivial) self-similarity [1]. In mathematics, a self-similar object is exactly or approximately similar to a part of itself (i.e., the whole has the same shape as one or more of the parts).

    Depending on authors, the term "maps" or the term "functions" may be reserved for specific kinds of functions or morphisms (e.g., function as an analytic term and map as a general term). mathematics See mathematics. multivalued A "multivalued function” from a set A to a set B is a function from A to the subsets of B.

    Given any non-decreasing function α on the real numbers, we can define the Lebesgue–Stieltjes integral () of a function f.If this integral is finite for all polynomials f, we can define an inner product on pairs of polynomials f and g by , = () ().

    en.wikipedia.org/wiki/Point_(geometry)

    In geometry, a point is an abstract idealization of an exact position, without size, in physical space, [1] or its generalization to other kinds of mathematical spaces.As zero-dimensional objects, points are usually taken to be the fundamental indivisible elements comprising the space, of which one-dimensional curves, two-dimensional surfaces, and higher-dimensional objects consist.
