root mean square deviation

基本解釋

Cpm is an overall capability index defined as the ratio of the specification spread (USL - LSL) to the square root of the mean squared deviation from the target.
Cpm是一個(gè)總體的能力指數(shù)，定義了均值偏離目標(biāo)值的均方差的平方根和規(guī)范寬度的之間的比值。
The calculation methods for root-mean-square deviation of concrete strength and mortar strength tested by rebound method are different founded through the comparison of the two methods.
通過對(duì)回彈法檢測(cè)混凝土強(qiáng)度、砌筑砂漿強(qiáng)度方法的比較，發(fā)現(xiàn)其計(jì)算標(biāo)準(zhǔn)差的方法有所不同。
Kalman-Filter-based optimal observation scheme is a Bayesian method, which improves observation locations by minimizing the expectation of the root mean square deviation(RMSD) of the analysis field.
最優(yōu)觀測(cè)方法是一種不需要直接同化觀測(cè)，而通過最小化分析場(chǎng)誤差方差理論值來選擇最優(yōu)觀測(cè)點(diǎn)的方法。

What we want to do now is compute the mean and variance of the portfolio-- or the mean and standard deviation, since standard deviation is the square root of the variance-- for different combinations of the portfolios.
我們現(xiàn)在要做的是,計(jì)算這個(gè)投資組合的均值和方差-,或者均值和標(biāo)準(zhǔn)差，因?yàn)闃?biāo)準(zhǔn)差的平方就等于方差-,這對(duì)任何投資組合都是一樣的。
