correlation    音标拼音: [k,ɔrəl'eʃən]
n. 相互关系,相关,关连

相互关系,相关,关连

correlation
自相关

correlation

correlation
n 1: a reciprocal relation between two or more things [synonym:
{correlation}, {correlativity}]
2: a statistic representing how closely two variables co-vary;
it can vary from -1 (perfect negative correlation) through 0
(no correlation) to 1 (perfect positive correlation); "what
is the correlation between those two variables?" [synonym:
{correlation coefficient}, {coefficient of correlation},
{correlation}]
3: a statistical relation between two or more variables such
that systematic changes in the value of one variable are
accompanied by systematic changes in the other [synonym:
{correlation}, {correlational statistics}]

Correlation \Cor`re*la"tion\ (-l?"sh?n), n. [LL. correlatio; L.
cor- relatio: cf. F. corr['e]lation. Cf. {Correlation}.]
Reciprocal relation; corresponding similarity or parallelism
of relation or law; capacity of being converted into, or of
giving place to, one another, under certain conditions; as,
the correlation of forces, or of zymotic diseases.
[1913 Webster]

{Correlation of energy}, the relation to one another of
different forms of energy; -- usually having some
reference to the principle of conservation of energy. See
{Conservation of energy}, under {Conservation}.

{Correlation of forces}, the relation between the forces
which matter, endowed with various forms of energy, may
exert.
[1913 Webster]


Energy \En"er*gy\, n.; pl. {Energies}. [F. ['e]nergie, LL.
energia, fr. Gr.?, fr. ? active; ? in ? work. See {In}, and
{Work}.]
1. Internal or inherent power; capacity of acting, operating,
or producing an effect, whether exerted or not; as, men
possessing energies may suffer them to lie inactive.
[1913 Webster]

The great energies of nature are known to us only by
their effects. --Paley.
[1913 Webster]

2. Power efficiently and forcibly exerted; vigorous or
effectual operation; as, the energy of a magistrate.
[1913 Webster]

3. Strength of expression; force of utterance; power to
impress the mind and arouse the feelings; life; spirit; --
said of speech, language, words, style; as, a style full
of energy.
[1913 Webster]

4. (Physics) Capacity for performing work.
[1913 Webster]

Note: The kinetic energy of a body is the energy it has in
virtue of being in motion. It is measured by one half
of the product of the mass of each element of the body
multiplied by the square of the velocity of the
element, relative to some given body or point. The
available kinetic energy of a material system
unconnected with any other system is that energy which
is due to the motions of the parts of the system
relative to its center of mass. The potential energy of
a body or system is that energy which is not kinetic;
-- energy due to configuration. Kinetic energy is
sometimes called actual energy. Kinetic energy is
exemplified in the vis viva of moving bodies, in heat,
electric currents, etc.; potential energy, in a bent
spring, or a body suspended a given distance above the
earth and acted on by gravity.
[1913 Webster]

{Accumulation}, {Conservation}, {Correlation}, & {Degradation
of energy}, etc. (Physics) See under {Accumulation},
{Conservation}, {Correlation}, etc.

Syn: Force; power; potency; vigor; strength; spirit;
efficiency; resolution.
[1913 Webster]

  • covariance(协变)和 correlation(相关性)如何理解他们的区别? - 知乎
    Correlation 存在的意义,则是将类似“10万”的数值概念相对化—— 考虑到 Portfolio 投资总额为1,000万,那么其潜在风险为1%(相对值),这对于多数投资者来说都处在一个可以接受的区间。
  • 如何理解皮尔逊相关系数(Pearson Correlation Coefficient)?
    Pearson相关性系数(Pearson Correlation) 是衡量向量相似度的一种方法。 输出范围为-1到+1, 0代表无相关性,负值为负相关,正值为正相关。
  • 相干性 (coherence )和相关性 (correlation) 有什么区别和联系?
    相关性 (Correlation,或称 相关系数 或 关联系数),显示两相关变量之间线性关系的强度和方向。在统计学中,相关的意义是用来衡量两个变量相对于其相互独立的距离。而 相干性 (Coherence), 与相关性计算得到的信息非常相似,都是衡量两个变量之间的相关程度,只是 相干性 多用于 频域计算
  • 如何理解皮尔逊相关系数(Pearson Correlation Coefficient)?
    Pearson 相关系数 (Pearson Correlation Coefficient,常简称 PCC,非 “Person 相关系数”),它是统计学中衡量 两个连续变量之间线性相关强度与方向 的经典指标,由英国统计学家卡尔・皮尔逊(Karl Pearson)提出,全称为 “皮尔逊积矩相关系数”(Pearson Product-Moment
  • 相关系数和R方的关系是什么? - 知乎
