A refinement of the arithmetic mean-geometric mean inequality Upper and lower bounds are given for the difference between the arithmetic and geometric means of n positive real numbers in terms of the variance of these... DI Cartwright,MJ Field - 《Proc.amer.math.soc》 被引量: 108发表: 1978...
Geometric programming problemArithmetic mean inequalityIn this paper, the researchers will present geometric arithmetic mean to solve non-linear fractional programming. To do this, we shall derive the inequality using the classical optimization theorem by developing the necessary and sufficient conditions ...
However, it is worth pointing out that the proof that a series is convergent does not necessarily mean that we can obtain its sum easily. In fact, the calculations of such summation can be tricky, and even impossible in many cases. There are many other convergence tests, including the term...
Calculate Geometric Mean in R, Geometric mean is the nth root of the product of n values of a set of observations. Geometric can be expressed as GM=(x1, x2, x3, ……, xn)1/n The advantage... The post Calculate Geometric Mean in R appeared first on finnstats. August 24, 2021 In...
Calculating Geometric Mean One problem with arithmetic mean is that it assumes the returns on the investment made at the beginning of each period. So, for each period the beginning investment amount is assumed to be the same. It ignores the compounding effect of investment returns made in the ...

returns the arithmetic mean of the data in slices. These methods are checked and will report RError(s), such as an empty input. This means you have to apply?to their results to pass the errors up, or explicitly match them to take recovery actions, depending on the error variant....
