This paper describes a consultancy problem where the question was to compare the variability of two groups of plants using several variables of widely differing types. The two-stage approach adopted is uncommon, and may be more generally useful to any analysis where variables are not commensurate....
Within-group variation (sometimes callederror grouporerror variance) is a term used in ANOVA tests. It refers to variations caused by differences within individual groups (or levels). In other words, not all the values within each group (e.g.means) are the same. These are differencesnot cau...
standard procedure i.e. multiplying branch alternative (dummy values) times the explanatory -individual specific- variables in order to "generate" this variability. That's what you might try, but be dilligent enough with the results you get. Are they really significantly different than mlogit(LR...

We suggest disease-specific reference targets to reduce normal inter-subject anatomical variability while at the same time enhance pathologically-induced differences between groups. These targets can be created by averaging subjects following linear registration, and we propose to use nonlinear registration ...
To analyze the variability within a single group of data, which statistical measure is appropriate? A. Standard deviation B. Variance C. Range D. Interquartile range 相关知识点: 试题来源: 解析 A。标准差用于衡量一组数据的离散程度,适合分析单个组内数据的变异性。方差是标准差的平方,也可以衡量...
Results indicate that variability of exposure is driven mainly by the individual compared with the aggregate variation and that biomarker levels perform fairly accurately in discriminating population-level consumption of fruits and vegetables. 展开
Consequently, this limitation may have introduced some additional variability in the data and future research should aim to control for this, where possible. 5. Conclusions In summary, the present study developed a comprehensive physical testing battery for golfers and showed that the strongest ...
