1) regression on order statistics 次序统计量回归 1. Objective: the purpose of this study was to compare the performance of regression on order statistics(ROS) and substitution methods in estimation of nondetects. 目的:比较用于处理包含未检出值的痕量测定数据的次序统计量回归方法与经典替换方法的估计...

For 1⩽i⩽n, let {Xi:n} denote the ith order statistic among X1,…,Xn. In this paper, we characterize the distributions for which the regression E((X1:n+⋯+Xn:n)/n|Xk:n=x) is a linear function of x.关键词: Order statistics Regression function Characterization ...
A new frequency weighted technique for model reduction is explored. The new technique is based on pursuing similar effect of eigenvalues of weighted augmented input and output realization matrices,X_{en}andY_{en}, respectively. Unlike the Enns technique, the method yields not only stable reduced-...
The dependent variable is the order response category variable and the independent variable may be categorical or continuous. In SPSS, this test is available on the regression option analysis menu. Do gender and race influence happiness as categorized by the XYZ survey? Does age relate to the ...

The Shapiro–Wilk W test, which depends on the covariance matrix between the order statistics of the observations, can also be used with 50 samples, and has been recommended by Altman (1999) and by Ghasemi and Zahediasl (2012). The Python command stats.normaltest(x) uses the D’Agostino–...
In the preceding example, using a cubic fit increased both statistics compared to a linear fit. (You can compute adjusted R2 for the linear fit for yourself to demonstrate that it has a lower value.) However, it is not always true that a linear fit is worse than a higher-order fit: ...
(Global Moran's I)tool on the model residuals to see if the under/over-predictions are clustered or not. In order to provide at least some information about residual clustering in the case where none of the models pass all of these criteria, theSpatial Autocorrelation (Global Moran's I)...
Including such a variable in the model may have an effect on the overall significance of the model. If only the 90 percent confidence interval overlaps with 0, the explanatory variable may be included in the model provided the other global statistics are significant. Ideally, the confidence ...
