变异系数

The coefficient of determination (r2 ) expresses the extent to which the changes in explain the variation in.

判定系数(r2 )以x 的变化来解释 y 改变之程度。即是衡量变数 y 由x所解释之百分比，r2 也意味著 y 变异之部份可由自变数 x 解释的百分比。

In the study on the relationship between different grid sizes and variogram of the pupae, the variation in the range, the intensity of local spatial continuity and the sill was very low or non-existent when the grid size was 5m, 6m or 7m, the value of the decisive coefficient was more bigger when the grid size was 5m, so, it is ideal grid size.

对不同样方大小的变异曲线图进行比较得知：样方边长分别为5、6、7m时，变程、空间局部连续性强度和基台值的变化幅度均很小，几乎相等，而样方边长为5m时的决定系数较大，此样方为最适样方大小。

UPGMA cluster analysis and genetic differentiation among populations showed that there had closer genetic relationship between Gongliu and Xinyuan populations and between Huocheng and Yumin populations and lower genetic variation between the populations.

UPGMA聚类分析和群体间遗传分化系数显示，巩留群体和新源群体之间，以及霍城群体和裕民群体之间，遗传关系最近，群体间遗传变异最低。

Using leisure attitude and leisure motivation as prediction variables to build a regression model, leisure attitude and leisure motivation both correlated with leisure satisfaction with multiple correlation coefficient of .997, and 99.1% of the variability in leisure satisfaction could be accounted for by the variability in leisure attitude and leisure motivation considered together.

若以休闲态度与休闲动机为预测变项建立复回归方程式，结果显示，休闲态度、休闲动机共同与休闲满意的相关系数为。997，休闲态度与休闲动机对休闲满意的变异解释高达99.1%。

Methods Fitting two-level random coefficient model and sequence effect to estimate the treatment effect and its variation between individuals.

通过两水平随机系数模型以及顺序效应的拟合，估计处理效应的大小及其在个体间的变异。

The range of variation of differentiation coefficient of morphological traits among population was between 11.85% to 28.34%.

结果表明，板栗种群间的方差分量占总变异的10.97%，种群内的占41.57%，7个性状种群间的表型分化系数变幅在

Results the parameter estimates and it's stability of linear regression models is associated with the variation of explanatory variable between and within level 2units,and the relationship of parameter estimates and it's stability between linear regression models and variance component model is associated with level 2 residual variance or intatra-unit correlation.

结果 线性回归模型参数估计以及估计的稳定性与自变量在水平2单位间和水平2单位内的变异大小有关，线性因归模型与方差成分模型参数估计及其稳定性的关系与水平2残差方差或单位内相关系数大小有关。

In particular, we propose conditional correlations with a bivariate hyperbolic distributions method to dominate GSV hedge ratios.

特别的，我们提出在双重双曲线分配方法下的条件关系系数，并且应用在控制广义的半变异数期货避险值上。

Karyotypic findings showed that all cultivars were mixoploid with chromosome number ranging from 49 to 57, and 54 was the most frequent number observed.

结果表明：（1）17个栽培小菊均为混倍体，染色体数在49～57之间变异，以54条为主；（2）染色体呈现多态性：多数品种由中部、近中部和近端部着丝粒染色体组成；最长与最短染色体的比值为1.62～2.39；臂比＞2的染色体所占的比率为11.11%～29.62%；核型不对称系数为59.74%～63.37%；3个地被菊品种和'奥运橙光'、'金陵白凤'（2n=53）核型类型为&2B&，其它品种为&2A&型。

Result: The genetic similarity coefficient was varied from 85.4% to 98.4%. The variation of protocorm, germination and monoleaf were rather more notable than that of bileaf and inflorescence.

结果：发现不同阶段内遗传相似系数较大，在85.409 3%～98.360 6%，其中在原球茎、萌芽期和一叶期存在的变异比两叶期、开花期要显著，但程度都极其微弱。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
