After comparing the two type of tests,we came to some conclusions.The tests based on binomial test can be regarded as some kind of permutation tests under certain definition of "permutaton".If the tests are related to statistics,then whether they can be viewed as permutation tests depends on if the value of the probability,p,is known where p is the population parameter in the null hypothesis.For tests like Kolmogorov goodness-of-fit test,since the statistics is calculated based on empirical distribution function,hence no matter how we repermutate the observations,the order statistics is the same.This kind of tests can't be regarded as permutation tests.
我们得到的结论为:在一般的无母数检定中,如果检定与binomial test相关,基本上都可以视作排列检定的一种;与卡方检定相关的检定,基本上和p值已知或是未知有关,这个p值为原始假设下所要检定的母体机率值;其他检定如Kolmogorov goodness-of-fit test,由於统计量的值是根据empirical distribution function决定,而不论如何重新排列样本,其顺序统计量都不变,所以无法视为一种排列检定。

Having discussed Wallis'interpolation in great detail, the paper shows that Wallis mainly relied on incomplete induction and analogical inference to obtain his results, an approach which was key to the creation of many important algorithms during the considered period. A comparison between Wallis'method and previous interpolations is then made and the influence of Wallis' thinking style embodied in his interpolation on Newton's invention of binomial theorem is clearly revealed.

Consider the dependencies between the coefficients and their parents, a non-Gaussian bivariate distribution is given, and corresponding nonlinear threshold function is derived from the model using Bayesian estimation theory. According to non-subsampled Contourlet transform and bivariate threshold function, a novel Non-Subsampled Contourlet Transform based on Bivariate threshold function for image denoising is proposed. This scheme achieves enhanced estimation results for images that are corrupted with additive Gaussian noise over a wide range of noise variance.

The model includes that the relationship between median diameter, as well kinetic energy, of raindrop and rainfall intensity obeys logarithmic function, the critical slope degree of soil erosion is 38.4°~43.0° in test area and the best multiple index of rainfall erosivity value is /100. Employing the prediction model, the soil erodibility value, the accelerated value of excavation slope, roadbed slope, construction site, borrow pit, service road and other temporary occupation land and the loss-spoil ration of waste pile were examined. Finally, the integrated soil and water conservation measures in highway construction project have been suggested.

First, it was to obtain two binary images from segmenting image by two thresholds. Second, erosion, opening and closing were done to the two images according to some knowledge of the shape and location of the objects in the image that we have already known. Last, the edge information from the image segmented by a high threshold was put into the image segmented by a low threshold. It is the way to segment and discern circular objects accurately from the complex image and can greatly improve the accuracy rate of discerning.
