the index of dispersion, dispersion index, coefficient of dispersion, relative variance, or variance-to-mean ratio (VMR), like the coefficient of variation...

dispersion, a quantifiable variation of measurements of differing members of a population Index of dispersion, a normalized measure of the dispersion...

Morisita's overlap index, named after Masaaki Morisita, is a statistical measure of dispersion of individuals in a population. It is used to compare overlap...

statistics, dispersion (also called variability, scatter, or spread) is the extent to which a distribution is stretched or squeezed. Common examples of measures...

general, dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency; sometimes the term chromatic dispersion is used for...

times distorts the shape. Modal dispersion limits the bandwidth of multimode fibers. For example, a typical step-index fiber with a 50 μm core would be...

well in describing dispersion. Sellmeier coefficients are often quoted instead of the refractive index in tables. Because of dispersion, it is usually important...

low-dispersion glass. Special low dispersion glass (SLD glass) and extraordinary low-dispersion glass (ELD glass) are glasses with yet lower dispersion (and...

variation is λ − 1 / 2 , {\textstyle \lambda ^{-1/2},} while the index of dispersion is 1.: 163  The mean absolute deviation about the mean is: 163  E...

minimizes modal dispersion. Multi-mode optical fiber can be built with either a graded-index or a step-index profile. The advantage of graded-index multi-mode...
