  2. Geometric median - Wikipedia

    en.wikipedia.org/wiki/Geometric_median

    For the 1-dimensional case, the geometric median coincides with the median.This is because the univariate median also minimizes the sum of distances from the points. (More precisely, if the points are p 1, ..., p n, in that order, the geometric median is the middle point (+) / if n is odd, but is not uniquely determined if n is even, when it can be any point in the line segment between the two ...

  3. Median (geometry) - Wikipedia

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

    In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. Every triangle has exactly three medians, one from each vertex, and they all intersect at the triangle's centroid .

  4. Radon's theorem - Wikipedia

    en.wikipedia.org/wiki/Radon's_theorem

    Geometric median. The Radon point of three points in a one-dimensional space is just their median. The geometric median of a set of points is the point minimizing the sum of distances to the points in the set; it generalizes the one-dimensional median and has been studied both from the point of view of facility location and robust statistics ...

  5. Fréchet mean - Wikipedia

    en.wikipedia.org/wiki/Fréchet_mean

    The geometric mean is the corresponding Fréchet mean. Indeed f : x ↦ e x {\displaystyle f:x\mapsto e^{x}} is then an isometry from the euclidean space to this "hyperbolic" space and must respect the Fréchet mean: the Fréchet mean of the x i {\displaystyle x_{i}} is the image by f {\displaystyle f} of the Fréchet mean (in the Euclidean ...

  6. Geometric mean - Wikipedia

    en.wikipedia.org/wiki/Geometric_mean

    The geometric mean has been used in choosing a compromise aspect ratio in film and video: given two aspect ratios, the geometric mean of them provides a compromise between them, distorting or cropping both in some sense equally. Concretely, two equal area rectangles (with the same center and parallel sides) of different aspect ratios intersect ...

  7. Median (disambiguation) - Wikipedia

    en.wikipedia.org/wiki/Median_(disambiguation)

    Median (statistics), in statistics, a number that separates the lowest- and highest-value halves; Median (geometry), in geometry, a line joining a vertex of a triangle to the midpoint of the opposite side; Median (graph theory), a vertex m(a,b,c) that belongs to shortest paths between each pair of a, b, and c

  8. Fermat–Weber problem - Wikipedia

    en.wikipedia.org/wiki/Fermat–Weber_problem

    In mathematics, statistics, and operations research, the Fermat–Weber problem is either of two closely related problems: . Geometric median, the problem of finding a point minimizing the sum of distances from given points

  9. Geometric distribution - Wikipedia

    en.wikipedia.org/wiki/Geometric_distribution

    The median of the geometric distribution is ⌈ ⁡ ⁡ ⌉ when defined over [9] and ⌊ ⁡ ⁡ ⌋ when defined over . [ 3 ] : 69 The mode of the geometric distribution is the first value in the support set.
