The test of homogeneity for intraclass correlation coefficients has been one of the active topics in statistical research. Several chi-square tests have been proposed to test the homogeneity of intraclass correlations in the past few decades. The big concern for them is that these methods are seriously biased when sample sizes are not large. In this thesis, data driven approaches are proposed t...

BACKGROUND AND PURPOSE Dilated Virchow-Robin spaces are an emerging neuroimaging biomarker, but their assessment on MRI needs standardization. METHODS We developed a rating method for dilated Virchow-Robin spaces in 4 brain regions (centrum semiovale, basal ganglia, hippocampus, and mesencephalon) and tested its reliability in a total of 125 MRI scans from 2 population-based studies. Six inve...

background: alcohol consumption is one of the main health problems in most countries. the purpose of the present study is to evaluate the reliability and validity of alcohol use disorders identification test (audit). methods: by employing the method of available sampling, 70 alcoholic patients were included as case group and 70 normal age, gender and education matched individuals were also incl...

in the present work, a modified correlation is presented for the second virial coefficients of both polar and nonpolar fluids based on the corresponding states principle. the second virial coefficients of gaseous polar and non-polar compounds were calculated and compared with experimental data and with other correlations. comparisons with the existing correlations show that the present work is ...

BACKGROUND Due to the distinct cultural and language differences that exist in Switzerland, there is little information on the dietary intake among the general Swiss population. Adequately assessing dietary intake is thus paramount if nutritional epidemiological studies are to be conducted. OBJECTIVE To assess the reproducibility and validity of a food-frequency questionnaire (FFQ) developed ...

The food industry is characterized by a constant increase in value. purpose of this study to identify the most popular marketing forms used analyzed enterprises, which were producers selling online among local community and identification correlation variables with age companies. survey was carried out use CATI (Computer Assisted Telephone Interviewing) method, research tool questionnaire. Chi-...

Extended Abstract. Suppose n i.i.d. observations, X1, …, Xn, are available from the unknown distribution F(.), goodness-of-fit tests refer to tests such as H0 : F(x) = F0(x) against H1 : F(x) $neq$ F0(x). Some nonparametric tests such as the Kolmogorov--Smirnov test, the Cramer-Von Mises test, the Anderson-Darling test and the Watson test have been suggested by comparing empirical ...

Repeatability and reproducibility indices are often used in gait analysis to validate models and assess patients in their follow-up. When comparing joint kinematics, their interpretation can be ambiguous due to a lack of understanding of the exact sources of their variations. This paper studied four indices (Root Mean Square Deviation, Mean Absolute Variability, Coefficient of Multiple Correlat...

ABSTRACT:-This paper presents a new algorithm to scramble color image using voiceprint and linear predicative coding (LPC). The speech signal pass through pre-processing stage which includes sampling and segmentation into many frames. All frames are windowed using rectangular window and fed to linear predicative predicator, the linear predicator is used to obtain the coefficient of the p th ord...

soil and water salinity in arid and semi-arid regions, is one of the most important stresses, can severely limit crop production. black cumin (nigella sativa l.) is annual important herbal plant in rununculaceae family that sense to salinity. this study was conducted to evaluate the effects of the priming on seed germination of black cumin under saline stress. the experiment was carried out as ...
