Linear regression

The Mann-Kendall statistic, the Spearman statistic and the least-square regression method were chosen to detect trend in a time series for the research work. The Mann-Kendall rank statistic is a non-parametric test, which can be used to test for the existence of a linear trend while the Spearman’s test confirms the result. In order to test the existence of a linear trend, the data set was divided into years) and short-range study (36 to 50 years) and analysed. A long-term…

Introduction Lead (Pb) contamination is a pervasive issue in many low-income neighborhoods throughout the United States. The toxicity of lead poses significant risks to human health, and proves to be especially harmful for children in terms of cognitive and physical development. Lead in the environment is primarily related to a legacy of anthropogenic sources including leaded gasoline, leaded paint, and various industrial applications. Although the presence of heavy metals is ubiquitous in the…

Neubert, M.J. & Halbesleben, K. (2015). Called to commitment: An examination of relationships between spiritual calling, job satisfaction, and organizational commitment. Journal of Business Ethics, 132, 859-872. DOI 10.1007/s10551-014-2336-z Neubert and Halsbesleben (2013) conducted a study on the role of spiritual calling on employee job satisfaction and organizational commitment. A sample of 771 working American adults participated in the quantitative study, which measured spiritual calling…

minutes and left to stand for 2 hours at room temperature. The absorbance of the supernatant solution was determined at 725 nm using 90% aqueous methanol as a solvent blank. A gallic acid standard curve was prepared and the equation derived by linear regression (y =36.84 x+0.1069) was used to determine the TPC of each extract in mg of gallic acid equivalents/g of extract (mg GAE/g). The experiment was performed in triplicate and TPC was reported as the average value of 3 trials ± the standard…

for drug (Rf value of Cilnidipine and Chlorthalidone was 0.75 and 0.47 respectively). Densitometric analysis of Cilnidipine and Chlorthalidone were carried out in the absorbance mode at 230 nm. The linear regression analysis data for the calibration plots of Cilnidipine and Chlorthalidone showed good linear relationship with r2 = 0.991 for CILN and r2 =0.997 for CHLO , with respect to peak area in the concentration range 800-2400 and 1000-3000 ng per spot, respectively. The method was validated…

temperature and mass on metabolic rate of the female mice were measured by monitoring the oxygen consumption in a specific time interval, using static respirometry. The data for several different groups was then collected and the least square linear regression from a log mass-log MRMS plot at 30°C, yielded a slope of. At 10°C, majority of the mice exhibited the highest metabolic rates. At 10°C, the mean MRMS was. The final results for this experiment depicted that body mass of an organism and…

1. Previous research and authors’ rationales for conducting their study 100 word minimum The article contained numerous references to studies conducted in reference to people with Post Traumatic Stress Disorder and Severe Mental Illness and the abnormally high rates of PTSD amongst people with Severe Mental Illness. For example the normal rates of PTSD amongst the subjects tested without SMI was 3.5%. Subjects that suffered from SMI had a higher rate of PTSD at around 28% to 43%. The…
