Abstract: According to the empirical evidence, financial returns show leptokurtosis, skewness and heavy-tailness. Regarding this behavior, we apply normal mixture mean variance distributions for ...
Abstract: Whilst many common phase distributions have well-defined closed-form variance expressions, the well-known Rician phase (or Blachman-Bennett) distribution does not have any similar known ...
Analysis of variance is sensitive to the distribution of the error term. If the error term is not normally distributed, the statistics based on normality can be ...
Variance is a statistical calculation that numerically describes the amount of variation in a data set. If values in a data set wildly fluctuate, variance would be high and predictions based on the ...
ABSTRACT: The Edinburgh Postnatal Depression Scale (EPDS) is widely used in epidemiological, research, and clinical contexts. Although it has clearly established cut-off points, its psychometric ...
