Basically, it tells you how equal or unequal your red blood cells are in … WebFeb 12, 2024 · A coefficient of variation, often abbreviated as CV, is a way to measure how spread out values are in a dataset relative to the mean. It is calculated as: CV= σ / μ where: σ = standard deviation of dataset μ = mean of dataset In its simplest terms, the coefficient of variation is simply the ratio between the standard deviation and the mean.
WebMay 10, 2024 · E ( Y) = λ μ X where λ is the Poisson mean and μ X is the mean of the size-distribution. Var ( Y) = λ ( μ X 2 + σ X 2), taking σ X 2 as the variance of the size-distribution. This suggests that the coefficient of variation of a compound Poisson would be. c Y = μ X 2 + σ X 2 λ μ X 2 = 1 + c X 2 λ = c N 1 + c X 2.
