答:算术级数增长与几何级数增长原本来源于马尔萨斯的人口理论。其中算术级数增长是指随着时间的推移,每年增加的数目是固定的,历年的总数目排列为等差数列的形式,假设第一年基数为2,每年固定增长的数目为1,则第二年增长的总人数则为3,以此类推。几何级数增长是指随着时间的推移,其增长数目是按几何级数增加,历年的总数...
The geometric average return is also sometimes known as the compound annual growth rate or time-weighted rate of return since it takes the compounding effect of time on the portfolio's average performance into account. Below is the basic formula for calculating geometric average return of a ...
Those extra 10 birds come from the geometric nature of the growth. The following year, instead of 1,300 birds, you'd have 1,331 birds, now with 31 more birds than arithmetic growth would yield. The number of "extra" birds will keep getting larger, as ...
identical to the geometric mean of the growth rates (geometric mean fitness), which is usually different from the simple arithmetic mean of growth rates... Y Jin,VAA Jansen - 《Researches on Population Ecology》 被引量: 206发表: 1996年 A refinement of the arithmetic mean-geometric mean inequa...
The arithmetic mean does not represent the actual growth. According to the actual figures, the total number of clients at the end of the three years should be: 100 000 000 * 1.015 * 1.020 * 1.025 = 106 118 250clients. This is an example of a case where the geometric mean is the app...
In the case of a discrete domain of definition with equal intervals, it is also called geometric growth or geometric decay , the function values forming a geometric progression . 在定义域为离散的且等差 的情况下,也称作几何增长 或几何衰减 (函数值是一个等比数列 ) 。 ParaCrawl Corpus In 200...

it is used in stock indexes. because many of the value line indexes which is used by financial departments use g.m. it is used to calculate the annual return on the portfolio. it is used in finance to find the average growth rates which are also referred to the compounded annual growth...
That’s because the geometric mean formula takes into account earnings and compounding growth from one year to the next. The formula for the arithmetic mean does not.
The resulting geometric mean, or acompounded annual growth rate(CAGR), is 20.6%, much lower than the 35% calculated using the arithmetic mean. Limitations of Using the Geometric Mean in Analysis One problem with using the arithmetic mean, even to estimate the average return, is that the arith...
