Distributions with CV 1 (such as an Erlang distribution) are considered low-variance, while those with CV 1 (such as a hyper-exponential distribution) are considered high-variancecitation needed. Vmn is called a V-statistic of degreem. , more tightly clustered around the mean).

This allows you to visually understand where price action is, relative to its historical statistical distance.

For samples x1, . It is also commonly used in fields such as engineering or physics when doing quality assurance studies and ANOVA gauge RR,citation needed by economists and investors in economic models, and in neuroscience.
A symmetric kernel of degree 2 is a function h(x,y), such that h(x, y) = h(y, x) for all x and y in the domain of h.
If, for example, the data sets are temperature readings from two different sensors (a Celsius sensor and a Fahrenheit sensor) and you want to know which sensor is better by picking the one with the least variance, then you will be misled if you use CV.
