Over the past decades, various methods for comparing the means of two log-normal have been proposed. Some of them are differing in terms of how the statistic test adjust to accept or to reject the null hypothesis. In this study, a new method of test for comparing the means of two lognormal populations is given through the generalized measure of evidence to have against the null hypothesis. Howe...

A new method for detecting significant p-values is described in this paper. This method, based on the distribution of the m-th order statistic of a U(0, 1) distribution, is shown to be suitable in applications where m → ∞ independent hypothesis are tested and it is of interest for a fixed type I error probability to determine those being significant while controlling the false positives. Equiva...

In this paper, we propose a speech enhancement method based on spectral magnitude estimation. We modify the noise estimation from the minimum statistics method and combine with a maximum a posterior (MAP) decomposition, using the Rice-conditional probability and a non-Gaussian statistic model of the speech. We derive two versions of magnitude decomposition and magnitude-phase decomposition and ...

The statistical method in a comparative study in which the standard treatment is theoretically or practically superior to the others has been investigated for a matched-pairs design. We derived this statistical method from one based on the maximum likelihood and score methods. Here we have shown that the score test statistic is algebraically the same as the statistic from the maximum likelihood...

one out of eight women face with the problem of breast cancer in her life. it is the second causes of women death in the world. detection of breast cancer metastasis at the earliest stage is important to predict and control of breast cancer progression. it can spread to the different parts of the body, such as are the bone, liver, and lung and etc. how and where does the breast metastasis grow ...

Hopkins statistic [@hopkins1954new] can be used to test for spatial randomness of data and detecting clusters in data. Although the method is nearly 70 years old, there persistent confusion regarding definition calculation statistic. We investigate its possible origin. Using most general statistic, we perform a small simulation verify distributional properties, provide visualization how calcula...

Map comparison methods are used to express the similarity between maps. They are amongst others used in validation and calibration procedures of spatial models. It is found that traditional map comparison methods do not distinguish small differences from large differences, which leads to comparison results that are not in accordance with human judgment. In this paper a relatively new method for...

The C-statistic, measuring the rank concordance between predictors and outcomes, has become a standard metric of predictive accuracy and is therefore a natural criterion for variable screening and selection. However, as the C-statistic is a step function, its optimization requires brute-force search, prohibiting its direct usage in the presence of high-dimensional predictors. We develop a smoot...
