Skewness and Kurtosis in Statistical Kinetics.
We obtain lower and upper bounds on the skewness and kurtosis associated with the cycle completion time of unicyclic enzymatic reaction schemes. Analogous to a well-known lower bound on the randomness parameter, the lower bounds on skewness and kurtosis are related to the number of intermediate states in the underlying chemical reaction network. Our results demonstrate that evaluating these hig...
متن کاملThreshold Selection for TOA Estimation Based on Skewness and Kurtosis in 60GHz Ranging System
Accurate localization has gained significant interests in the field of ranging, locating and tracking systems. Impulse Radio (IR) 60GHz signal is practically operated in the literature, because of its high resolution of time and multipath. In order to improve the precision of the Time of Arrival (TOA) estimation, a threshold selection algorithm based on a joint metric of the skewness and kurtos...
متن کاملthe effects of planning on accuracy and complexity of iranian efl students’ written narrative task performance
this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
15 صفحه اولThreshold Selection for 60 GHz TOA Estimation Based on Skewness and Kurtosis Analysis
Because of the high sampling rate, coherent Time of Arrival (TOA) estimation algorithms are not practical for low cost, low complexity 60 GHz systems. In this paper, energy detect (ED) based non-coherent TOA estimation algorithm is presented. The expected values of the skewness and kurtosis with respect to the signal to noise ratio (SNR) are investigated. It is shown that the ratio of kurtosis ...
متن کاملDensity-Based Skewness and Kurtosis Functions
New, functional, concepts of skewness and kurtosis are introduced for large classes of continuous univariate distributions. They are the first skewness and kurtosis measures to be defined directly in terms of the probability density function and its derivative, and are directly interpretable in terms of them. Unimodality of the density is a basic prerequisite. The mode defines the centre of suc...
