  • Kovarianca - Wikipedija, prosta enciklopedija

    Kovarianca (oznaka (,), včasih tudi ) je merilo, s katerim določamo, kako sta dve naključni spremenljivki povezani.Poseben primer kovariance je varianca, ki pa opisuje spreminjanje dveh spremenljivk, ki sta identični.

  • Covariance - Wikipedia

    In probability theory and statistics, covariance is a measure of the joint variability of two random variables. If the greater values of one variable mainly correspond with the greater values of the other variable, and the same holds for the lesser values, (i.e., the variables tend to show similar behavior), the covariance is positive. In the opposite case, when the greater values of one ...

  • Covariance - Definition, Formula, and Practical Example

    In mathematics and statistics, covariance is a measure of the relationship between two random variables. The metric evaluates how much - to what extent - the variables change together. In other words, it is essentially a measure of the variance between two variables

  • Covariance in Statistics: What is it? Example - Statistics ...

    Covariance in Excel: Overview. Covariance gives you a positive number if the variables are positively related. You’ll get a negative number if they are negatively related. A high covariance basically indicates there is a strong relationship between the variables.

  • Covariance matrix - Wikipedia

    In probability theory and statistics, a covariance matrix, also known as auto-covariance matrix, dispersion matrix, variance matrix, or variance–covariance matrix, is a matrix whose element in the i, j position is the covariance between the i-th and j-th elements of a random vector. A random vector is a random variable with multiple dimensions.

  • Covariance -- from Wolfram MathWorld

    Covariance. Covariance provides a measure of the strength of the correlation between two or more sets of random variates. The covariance for two random variates and , each with sample size, is defined by the expectation value

  • Covariance — Wikipédia

    En théorie des probabilités et en statistique, la covariance entre deux variables aléatoires est un nombre permettant de quantifier leurs écarts conjoints par rapport à leurs espérances respectives. Elle s’utilise également pour deux séries de données numériques (écarts par rapport aux moyennes).. La covariance est une extension de la notion de variance.
