Both symmetric (normal) and skewed (ex-Gaussian) distributions were examined. The ex-Gaussian distribution is particularly relevant because it is representative of skewed distributions found in experimental psychology, most notably reaction time data. Results indicate that when testing the hypothesis of ...

The bell-shaped curve isa common feature of nature and psychology. The normal distribution is the most important probability distribution in statistics because many continuous data in nature and psychology displays this bell-shaped curve when compiled and graphed. Is every normal curve bell-shaped? Bu...

lognormal or power law distributions [5,6], further increasing interest in the distribution. In this work we report observations of lognormal-like properties of Internet based human communication, but postulate that their origin is not due to multiplicative process but rather to human psychology. ...

The cognitive functions of the members of this group were basically stable and showed no Conclusion This study used the skewed t-distribution GMM model to identify different trajectories of cognitive decline and examined the factors that may affect cognitive function in elderly individuals. Our finding...
In linear scale it is a highly skewed distribution with a long tail in the high productivity side. We are still lacking a detailed and convincingmodel able to explain observed Log-Normal distributions鈥攖his is the gap this paper sets out to fill. Here, we propose a general explanation of ...
