In constructing a confidence interval for the mean difference of two independent populations, we may encounter problem having low coverage probability when there are many zeros in data, and non-zero values highly positively skewed. The violation normality assumption makes parametric methods inefficient such cases. this paper, jackknife empirical likelihood (JEL) adjusted (AJEL) proposed to cons...

A recently synthesized self-doped conducting oligomer, salt of bis[3,4-ethylenedioxythiophene]3thiophene butyric acid, ETE-S, is a novel promising material for green energy applications. Recently, it has been demonstrated that it can polymerize in vivo, in plant systems, leading to a formation of long-range conducting wires, charge storage and supercapacitive behaviour of living plants. Here we...

A proposed heat precipitation and thrombin interaction technic for fibrinogen isolation has been compared with a sulfite fractionation technic. All three methods exhibit a high degree of correlation. Fibrinogen, which has been separated from plasma by these technics, may be quantitated by the colorimetric modified biuret and phenol-biuret reaction. For direct measurement of fibrinogen, heat pre...

The variance of a random variable is σ. It is the measure of spread from the center. Therefore, how to accurately estimate variance (σ) has always been an important topic in recent years. In this paper, we consider a linear regression model which is the most popular model in practice. We use jackknife empirical likelihood (JEL) method to obtain the interval estimate of σ in the regression model...
