A novel method of colour image segmentation based on fuzzy homogeneity and data fusion techniques is presented. The general idea of mass function estimation in the Dempster-Shafer evidence theory of the histogram is extended to the homogeneity domain. The fuzzy homogeneity vector is used to determine the fuzzy region in each primitive colour, whereas, the evidence theory is employed to merge di...
We propose an encompassing test for non-nested linear quantile regression models and show that it has an asymptotic χ2 distribution. It is also shown that the proposed test is a regression rank score test in a comprehensive model under conditional homogeneity. Our simulation results indicate that the proposed test performs very well in finite samples. JEL classification: C12, C52
BACKGROUND Mixed effects logistic models have become a popular method for analyzing multicenter clinical trials with binomial data. However, the statistical properties of these models for testing homogeneity of odds ratios under various conditions, such as within-center and among-centers inequality, are still unknown and not yet compared with those of commonly used tests of homogeneity. METHO...
the main purpose of this article is, showing similar fluctuation of temperature series and their consistency with what happened in the global level. in addition, it determines new estimates of regional seasonal and annual temperature trends over iran, after the detection of artificial and natural non homogenous points of 33 synoptic stations for the period of 1960 2010. the 22 stations with sho...
BACKGROUND A frequently used statistic for testing homogeneity in a meta-analysis of K independent studies is Cochran's Q. For a standard test of homogeneity the Q statistic is referred to a chi-square distribution with K-1 degrees of freedom. For the situation in which the effects of the studies are logarithms of odds ratios, the chi-square distribution is much too conservative for moderate si...
This research objective was to determine the effect of using Educandy learning media on Japanese students’ outcomes in a state vocational high school Jakarta for academic year 2020/2021. study applied experimental quantitative method, with purposive sample technique 16 students. used one group Pre Test–Post Test design, and data collected then analysed descriptive inferential statistics. In pre...
In the present study, an attempt was made to compare the statistical tools used for analysing the data of repeated dose toxicity studies with rodents conducted in 45 countries, with that of Japan. The study revealed that there was no congruence among the countries in the use of statistical tools for analysing the data obtained from the above studies. For example, to analyse the data obtained fr...
