First moment about mean
WebMoment (mathematics) In mathematics, a moment is a specific quantitative measure, used in both mechanics and statistics, of the shape of a set of points. If the points represent mass, then the zeroth moment is the total mass, the first moment divided by the total mass is the center of mass, and the second moment is the rotational inertia. WebFeb 28, 2015 · The first moment gives a weight to higher frequencies and second moment even to more higher frequencies.
