Instantaneous coefficient of variation

Nettet19. aug. 2016 · I have tried using coefficient of variation. But because the temperature data varies from say 20-40 deg C, the mean would be high and standard deviation low, the coefficient of variation is very low. I wish to know an alternative in this case to give a proper representation. It would be great if you can help. Ex. 27.2 30.4 30.4 31.0 31.9 35.2. NettetI know that if the output is a linear combination of the inputs with coefficients equal to 1, I can come up with an estimate of the variance for the output by adding together the variances of the inputs. For example: y = x 1 + x 2 v a r ( y) = v a r ( x 1) + v a r ( x 2)

Nettet14. des. 2024 · 1 Answer. Sorted by: 1. The coefficient of variation (CV) is just the standard deviation (SD) divided by the mean,. Often, although not necessarily, it is expressed in percent terms. (A referee of a paper of mine commented that a CV of 2 was extraordinarily low. He was presuming that I meant 2%. NettetThe coefficients of variation, however, are now both equal to 5.39%. Mathematically speaking, the coefficient of variation is not entirely linear. That is, for a random variable , the coefficient of variation of is equal to the coefficient of variation of only when .
