An empirical likelihood ratio based goodness-of-fit test for skew normality Skew normal distributionIn this paper, an empirical likelihood ratio based goodness-of-fit test for the skew normality is proposed. The asymptotic results ... W Ning,G Ngunkeng - 《Statistical Methods & Applications》 被...
Commonly used regression tests of fit are also included in the comparisons. The results indicate that use of the plotting position pi = (i - .375)/(n + .25) yields a competitive regression test of fit for normality.doi:10.1080/00031305.1985.10479395Looney, Stephen W....
In in vivo experiments using a zebrafish model, nitrite was found to protect blood vessels from hypoxia-induced vascular leakage.These results are the first to demonstrate that nitrite plays a critical role in the protection of endothelial barrier function against hypoxic insult. Our findings show ...
Characterizations of normal distributions supporting goodness-of-fit tests based on sample skewness and sample kurtosis These results theoretically support the goodness-of-fit tests for normal distributions using the sample skewness and the sample kurtosis.Truc T. Nguyen... TT Nguyen,KT Dinh - 《Metri...
The results in Table 2 indicate that the LN distribution outperforms the mixture normal distribution. In fact, the fitted CDF in Figure 4 shows that the mixture normal distribution does not provide an adequate fit. The fact that the LN distribution has only three parameters adds an extra ...
: Some publications indicate the possibility of the influence of meal nutritional value on results of bioelectrical impedance, and of the relation between the long-term carbohydrate intake and body composition. The aim of the presented study was to evaluate the influence of long-term intake of ...
For example, classroom test results are usually normally distributed. An extreme example: if you choose three random students and plot the results on a graph, you won’t get a normal distribution. You might get a uniform distribution (i.e. 62 62 63) or you might get a skewed distribution...
Results First, statistical analysis was performed to see if quality of life expressed by the WHOQOL-BREF questionnaire is related to ODI. The result of Spearman's rank correlation coefficient rho = − 0.22 indicates a weak negative relationship. Moreover, the correlation between WHOQOL-BREF...
Inherent variability must be considered in designing empirical tests of normality, and differences in inherent variability must be considered in interpreting results. 展开 关键词: Rethinking allometry DOI: 10.1006/jtbi.1995.0050 被引量: 15 年份: 1995 ...
Working through the solution to the parameters θ_0 to θ_n using the process described above results in an extremely involved derivation procedure. There is indeed a faster solution. Take a look at the formula for the normal equation:
