Owen (1988) showed that the non-parametric empirical likelihood ratio under a linear constrain has an asymptotic chi-square distribution, same as in the paramet-ric case. This fact can be used to form (non-parametric, asymptotic) conndence intervals. We suggest here to use the non-parametric version of the Pearson's chi-square statistic instead of the likelihood ratio to form conndence interval...

monumental changes occurring on a daily basis have altered the world into a global village of expanding technology and shrinking geography in which preparing language learners for intercultural communication seems to be a sine qua non for modern language education. employing a cross-sectional design in its first phase, this study investigated the intercultural sensitivity and language proficien...

We report closed-form formula for calculating the Chi square and higher-order Chi distances between statistical distributions belonging to the same exponential family with affine natural space, and instantiate those formula for the Poisson and isotropic Gaussian families. We then describe an analytic formula for the -divergences based on Taylor expansions and relying on an extended class of Chi...

The main concern of this study was communication strategies (CSs) which are used to compensate for communication breakdown. The goals of this study were to examine whether proficiency level of Iranian students had any relationship with their choice of CSs. This research was descriptive in nature. The participants were 15 pre-intermediate and 14 intermediate EFL learners between 16 to 21years ol...
