In probability theory and statistics, the mathematical concepts of covariance and correlation are very similar. Notably, tthe is dimensionless while covariance is in correlxtion obtained by multiplying the units of the two variables. If Y always takes on the same values as X, we have the covariance of a variable with itself i. The correlation of a variable with itself is always 1 except in the te case betwedn the two variances are zero because X always takes on the same single value, in which corre,ation the correlation does not exist wto its computation would involve division by 0.

More generally, the correlation between two variables is 1 or —1 if one of them always takes on a value that is given exactly what is the correlation between two random variables a linear function of the other with respectively a positive or negative slope. Although the values of the theoretical covariances and correlations are linked in the above way, the probability distributions of sample estimates of these quantities are not linked in any simple way and they generally need to be treated separately.

Multiple random variables With any number of random variables in excess of 1, the variables can be stacked into a random vector whose i th element is the i th random variable. Varriables the variances and covariances can be placed in a covariance matrix, in which the i,j element is the covariance between the varoables th random variable and the j th one. Likewise, the correlations can be placed in a correlation matrix.

In this case the cross-covariance and cross-correlation are functions of the time difference:. Cerrar sugerencias Buscar Ranom. Configuración de usuario. Saltar el carrusel. Carrusel anterior.
