In this article a new parameter estimation method for symmetric stable distributions is presented, which is a variation of maximum likelihood type M-estimators. The estimator provides a joint estimation of shape parameter \\(\\alpha \\) , scale parameter \\(\\gamma \\) and location parameter ...
Also, it is optimal for a symmetric distribution (logistic) and, hence, less likely to bias selection for left or right skewness. We decided to set the benchmarks for the selector statistic Q1 based on the medians of the distribution of Q1 for the family of skew-normal distributions with...
We consider plots which can be used to check whether a distribution is symmetric about some point and which give information about possible deviations from symmetry. Simultaneous confidence bands for checking the accuracy of the plots are derived and compared. Tests that are related to the plots an...
An important feature of the distribution in Fig.1his that there is a correlation between site energy and entropy; this is known as the ‘compensation effect’ in literature on GB segregation106. As we have demonstrated in ref.51, this correlation permits substantial simplification of the mathemati...
The parameter ξ∈ R controls the skewness: ξ > 0 and ξ < 0 correspond to right and left skew respectively, and ξ = 0 to a symmetric distribution. Important special cases arise when: ξ = 0, Z is the (scaled) Student-tν distribution; ν→∞, Z is a skew-Normal distribution; ...

the RIFF is notified about the position of the rat and can react to it. This latency was 39.5 ± 11.8 ms, with a unimodal, bounded distribution (mean ± std, min=11.3 ms, max=61.5 ms,n=186). A complete description of the latencies in the RIFF is provided in the “Methods” ...
