Precision (statistics)
text:
In statistics, the precision matrix or concentration matrix is the matrix inverse of the covariance matrix or dispersion matrix, P = Σ − 1 .
For univariate distributions, the precision matrix degenerates into a scalar precision, defined as the reciprocal of the variance, p = 1 σ 2 . Other summary statistics of statistical dispersion also called precision
include the reciprocal of the standard deviation, p = 1 σ ; the standard deviation itself and the relative standard deviation;
