In descriptive statistics, there are two computational algorithms for determining the variance S2, of a set of observations : Algorithm 1: S2= - , Algorithm 2: S2= , where . It is interesting to discuss, which of the above formulas is numerically more trustworthy in machine numbers sets. I this paper, based on total effect of rounding error, we prove that the second Algorithm is better...

this study was motivated by the researchers’ goal to unfold the quality of the english translations of persian tourism industry texts and discover the most frequent error patterns the iranian non-native translators have committed in such texts. thus, the following research questions were addressed: 1) are the english versions of persian tourist guidebooks and multimedia compact discs provided b...

in this paper we propose a relatively new semi-analytical technique to approximate the solution ofnonlinear multi-order fractional differential equations (fdes). we present some results concerning to the uniqueness of solution of nonlinear multi-order fdes and discuss the existence of solution for nonlinear multi-order fdes in reproducing kernel hilbert space (rkhs). we further give an error an...

the significance of error analysis for the learner, the teacher and the researcher is now widely recognized. earlier studies of error analysis concentrated on intersystematic comparison of the “native language” and the “target language” and drew the required data largely from intuitions and impressionistic observations. this study was conducted on the basis of the following observations: (1) to...
