Abstract:

The correlations between longevity, functional longevity, stayability and selected milk, reproductive and type traits were estimated; it was done on the basis of estimated breeding values for longevity, functional longevity, dairy traits, reproductive traits and stayability rates at the age of 60, 72, 84, and 96 months. The correlation between breeding values for longevity and functional longevity was 0.69. The correlations between longevity and stayability at 60, 72, 84, and 96 months of age were around 0.75 (from 0.73 to 0.76) whereas the correlation with stayability at 48 months was conside

Abstract:

A statistical analysis of important DNA sequences and related proteins has been performed to study the relationships between monomers, and some general considerations about these macromolecules can be provided from the results. First, the most important relationship between sites in all the DNA sequences examined is that between two consecutive base pairs. This is an indication of an energetic stabilization due to the stacking interaction of these couples of base pairs. Secondly, the difference between human chromosome sequences and their coding parts is relevant both in the relationships betw

Abstract:

This article explores the statistical relationship between speed and stopping distance in transportation movements. The study aims to analyze how variations in vehicle speed influence the distance required to bring a vehicle to a complete stop. Using real-world data, various statistical methods, such as regression analysis, were applied to determine the strength and nature of the correlation. The findings suggest that the stopping distance increases significantly with speed, highlighting the importance of safe driving practices and road design in minimizing accidents.

Abstract:

Estimates of correlation between pairs of genes in co-expression analysis are commonly used to construct networks among genes using gene expression data. As previously noted, the distribution of such correlations depends on the observed expression level of the involved genes, which we refer to this as a mean-correlation relationship in RNA-seq data, both bulk and single-cell. This dependence introduces an unwanted technical bias in co-expression analysis whereby highly expressed genes are more likely to be highly correlated. Such a relationship is not observed in protein-protein interaction da

Abstract The potential ability of an ensemble prediction system (EPS) to represent its own varying forecast error provides strong motivation to produce an EPS over a less expensive deterministic forecast. Traditionally, this ability has been assessed by correlating the realized forecast error with the ensemble's dispersion. This paper revisits the limitations of the skill–spread correlation, but uses aspects of the correlation to introduce two metrics to assess an EPS's capacity to provide a reliable likelihood of its own error. Using a perfect EPS, skill–spread correlation is shown to be limi

This paper examined the relationship between junior secondary school certificate Integrated Science examination result and academic performance of Science students in senior secondary school certificate examination in Physics, Chemistry and Biology in Osun State, Nigeria. Three research hypotheses were generated to guide the study. Descriptive research design of ex-post facto type was adopted for this study. A Multistage stratified random samplings technique was used to select 300 SSS3 science students from the three senatorial district in Osun State, Nigeria. An inventory was used to collect

Abstract:

Testing the relationship between variables is an important part of educational research. The rest is commonly done by using the Pearson productmoment correlation coefficient. The basic question in determining the significance of an observed correlation is the likel ihood of the observed relationship occurring by chance, given that there is nor a true correlation. When only two variables are involved, the significance is determined by using the standard t or z statistics or by consulting a table (see, for example, Ferguson, 1981, Table D). The significance level obtained can be referred to as t

Abstract:

Background:The Inflow Performance Relationship (IPR) describes the behavior of flow rate with flowing pressure, which is an important tool in understanding the well productivity. Different correlations to model this behavior can be classified into empirically-derived and analytically-derived correlations. The empirically-derived are those derived from field or simulation data. The analytically-derived are those derived from basic principle of mass balance that describes multiphase flow within the reservoir. The empirical correlations suffer from the limited ranges of data used in its generatio

Magnetic susceptibility characteristics as well as the relationships between magnetic susceptibility and As, Hg, Cu, Pb, Cd, Cr were investigated in the typical contaminated areas of southern Jiangsu Province.It was found that the correlations between magnetic susceptibility and Cu, Pb were relatively significant, while the correlations between magnetic susceptibility and Cd, As were weak. Heavy metals in soils from industrial wastewater discharge were associated with the magnetic susceptibility, which showed better correlation than other pollution sources.The primary component analysis showed

We investigate the cross-correlations of return-volume relationship of the Bitcoin market. In particular, we select eight exchange rates whose trading volume accounts for more than 98% market shares to synthesize Bitcoin indexes. The empirical results based on multifractal detrended cross-correlation analysis (MF-DCCA) reveal that (1) the nonlinear dependencies and power-law cross-correlations in return-volume relationship are found; (2) all cross-correlations are multifractal, and there are antipersistent behaviors of cross-correlation for q=2; (3) the price of small fluctuations is more pers

This paper aims to investigate the causal relationship between unemployment and emigration in Lithuania using Granger – causality test. The research is based on annual data spanning the period of 2004–2012. The investigation encompasses two steps. Firstly, the authors have analyzed the Lithuanian position regarding relationship between unemployment rate and emigration in the context of the European Union countries; secondly, the causality between unemployment and emigration has been determined in the case of Lithuania. On the basis of the European Union countries statistical data, results of t

Abstract:

As the technology for simultaneously recording from many brain locations becomes more available, more and more laboratories are measuring the cross-correlation between single-neuron spike trains, and between composite spike trains derived from several undiscriminated cells recorded on a single electrode (multiunit clusters). The relationship between single-unit correlations and multiunit cluster correlations has not yet been fully explored. We calculated the normalized cross-correlation (NCC) between single unit spike trains and between small clusters of units recorded in the rat somatosensory
