C.of.V |
Usual estimate of the coefficient of variation (C.of.V=sd/mean ) |
mean |
observed mean |
sd |
observed standard deviation (based on N -1 in the denominator of the variance) |
N |

return the unbiased estimate of the coefficient of variation |
A function to calculate the usual estimate of the coefficient of variation or its unbiased estimate.
Returns the unbiased estimate for the standard deviation.
