查询词典 homogeneity of variance

These above problems, which are very important and valuable in agricultural crops area monitoring, are currently less researched. Hence, in this paper, seven types of common texture and five vegetation indices were respectively added into TM multispectral bands to classify using three different methods, which are Minimum Distance, Maximum Likelihood and Support Vector Machine, and analyze the effect on winter wheat identification accuracy by comparing the classification results. The contexture include Mean, Variance, Homogeneity, Contrast, Dissimilarity, Entropy, Variance, Angular Second Moment and Correlation, and the vegetation indices are RVI, SAVI, RDVI, NDWI and SLAVI.

为此，该文将平均值、方差、均一性、反差、相异性、熵、角二阶矩、灰度相关7种纹理信息以及比值植被指数、土壤调整植被指数、重归一化植被指数、植被液态水含量指数、有效叶面积植被指数5种植被指数信息分别加入到TM多光谱数据中，同时还进行了最佳波段选择，利用最小距离、最大似然和支持向量机3种方法进行分类提取小麦，研究了不同特征信息对小麦测量精度的影响。

After verifying the homogeneity of variances between the groups (verification of the variation coefficients), means were compared through an analysis of variance.

验证完组间变异的同质性后，均值通过方差分析进行比较。

This article first discusses the significance of homogeneity of variance, then studies the general method of transformation for homogeneity of variance on the relation between the data mean and the variance when population distribution is known ,and it uses the Mathematica software to analyse the variety rules between the parameter and the variance in the corresponding transformation.

从方差非齐性数据处理中的变换的必要性入手，根据数据均值与方差之间的关系研究了总体分布已知时的方差齐性变换的一般方法，并利用Mathematica软件分析相应变换中参数与方差之间的图形规律，最后介绍了总体分布未知时的BoxCox变换的一般原理。

Objective:To introduce a robust method for homogeneity of variance .

目的 ：介绍一种较为稳健的方差齐性检验方法。

The SPSS program was performed to test normality of the dataset, variance homogeneity between the groups, coefficients of variation and analysis of variance.

对全部杂交信号点的Cy3和Cy5背景信号值，用SPSS软件进行数据转换、正态性检验、方差齐性检验、变异系数分析和重复数据的方差分析。

The results were as follows:(1) The structures of the SLCS consisted of two independent factors, viz. Self-Competence and Self-Liking, and ratio of variance of self-competence was higher than self-liking.(2) The SLCS had adequate item validity, homogeneity reliability, construct validity and discriminative validity.(3) Self-competence of male undergraduates from arts and humanities showed higher than female ones, but self-competence of female undergraduates from engineering and technology showed higher than male ones.

结果发现：(1)删除原量表4个项目后由16个项目构成的&自我喜爱感／自我能力感量表&由自我能力感和自我喜爱感两个维度构成，且相对于自我喜爱感、自我能力感对中国大学生特质自尊结构具有更强的解释力；(2)中国大学生群体应用该量表具有较理想的项目区分度、内部一致性信度、构想效度和区分效度；(3)男女大学生的自尊体验在总体上无显著差异，但文科类男生的自我能力感显著高于女生，而工科类女生的自我能力感显著高于男生。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
