在数学中ratio和proportion只有两个区别,分别是意思不同和强调内容不同:一、意思不同 1、proportion构成比;比例通常以100%为比例基数,用来说明各构成部分在总体中所占的比重或分布,比如什么东西在什么中占的比例很大 。2、ratio意思是比,比率。二、强调不同 1、proportion强调一物与他物在数量、大...
2、ratio:Ratio is the ratio between different categories of data in a sample (or population). 比率(ratio)是样本(或总体)中各不同类别数据之间的比值,由于比率不是部分与整体之间的对比关系,因而比值可能大于1。三、侧重点不同 1、rate:rate是百分比的意思。2、ratio:ratio是比例几比几。
We defined exposure as death or serious illness in older children and partners in the first trimester or in the 6 months before conception. Sex ratio at birth was defined as the proportion of male live births. RESULTS: During the study period, there were 1,349,099 singleton live births (...

[Pax6 and Pax6(5a)] with different DNA-binding properties.In vitrostudies have shown that the PAI subdomain of Pax6 binds preferentially to a consensus sequence (P6CON) [7] but that PAI subdomain disruption in Pax6(5a) allows the RED subdomain to bind an alternative sequence (5aCON) [6...
Sex ratio theory is concerned with the adaptive consequences of sex-biased parental allocation to offspring13,14, with the processes generating sex ratio bias after birth receiving less theoretical and empirical attention15. Here, we use a demographic pathway model to quantify ASR variation among avia...
although an optimum molar ratio varying from 6:1 to 13:1 has been employed by other researchers[34]. A molar ratio higher than the optimum value reduces the yield and makes the separation process of esters and glycerol difficult. High molar (40:1) is needed where supercritical methanol is ...
6 So why did Sharpe choose the standard deviation to adjust excess returns for risk, and why should we care? We know that Markowitz understood variance, a measure of statistical dispersion or an indication of how far away it is from the expected value, as something undesirable to investors....
