The geometric mean of the distribution of a random variable is the exponentiation of the mean of the natural logarithmThe geometric mean is the natural parameter of interest for a lognormal distribution because the distribution of a ratio of lognormal random variables has a known lognormal distribution and the geometric mean of a lognormal ratio is equal to the ratio of the individual. Where n is number of numbers and X1Xn are the numbers from the first to the n-th. The geometric mean is also referred as the compounded annual growth rate as the average rate of return values are calculated based on the product of the terms.
Instead the accepted definition of the GCV is GCV sqrt exp s 2 1 which is the definition that is used in SAS.
The geometric mean ratios for each dose level are compared to the reference dose. Other ways to compute the geometric mean You can use the DATA step to log-transform the data use PROC MEANS to compute the descriptive statistics of the. Instead the accepted definition of the GCV is GCV sqrt exp s 2 1 which is the definition that is used in SAS. The geometric mean ratios for each dose level are compared to the reference dose.
