How should I calculate a within-subject coefficient of variation? In the study of measurement error, we sometimes find that the within-subject variation is not uniform but is proportional to the magnitude of the measurement. It is natural to estimate it in terms of the ratio within-subject standard deviation/mean, which we call the within-subject coefficient of variation. In our British. Applications of the Coefficient of Variation . When used to evaluate investment risk, COV can be interpreted similarly to the standard deviation in modern portfolio theory (MPT).But the COV is. The calculations are performed according to the general methodology given by Machin et al., 2009. It is assumed that the calculation of the Coefficient of variation uses the Logarithmic method. Note that the calculation does not include a null hypothesis value or a factor for power (1âÎē). Therefore the estimated sample size does not give a. We say that there is greater variation in their consumption of meat. The observations about the quantity of meat are more dispersed or more variant.
