Skew‐normal distributions extend the traditional normal model by incorporating a parameter that accounts for asymmetry, thereby providing a more flexible framework for modelling real‐world data.

We point out that the skew-normal distributions and their limits are exactly the distributions of order statistics of bivariate normally distributed variables. The moment problem of powers of ...

A recent comparative analysis of alternative interval estimation approaches and procedures has shown that confidence intervals (CIs) for true raw scores determined with the Score method—which uses the ...

In the Moments table, N is the number of nonmissing observations, Mean is the arithmetic mean, Std Dev is the standard deviation, and Variance is the variance. Skewness and Kurtosis are both measures ...

The normal distribution is a concept in statistics that assumes all values are distributed in the same pattern. It requires symmetry and consistent proportions in the distribution of values. Normal ...
