In this work, we study the asymptotic distribution of the normalized sum of independent, identically distributed random variables under the finite mixture models. In the Theorem we give necessary conditions for a distribution function of a mixed population with k components to belong to the domain of attraction of an α-stable distribution, by assuming that each component of the mixture also per...
Resilience is defined as the system ability to keep an acceptable performance level against a sever disturbance and to return to a stable condition in a suitable time. Occurrence of inconvenient weather conditions and natural disasters, which are growing in number and severity during the last years, has always led to damages and wide outage throughout the distribution network. Therefore the ass...
BACKGROUND Previous research has reported that the mean of depressive symptoms is stable in the general population through middle adulthood. To understand the stability of depressive symptoms during middle adulthood, we investigated the nature of the distribution of depressive symptoms. METHODS We analyzed 24,890 subjects aged 15 to 84 years who participated in the Active Survey of Health and...
In this work, a linear procedure to perform the intensity normalization of FP-CIT SPECT brain images is presented. This proposed methodology is based on the fact that the histogram of intensity values can be fitted accurately using a positive skewed α-stable distribution. Then, the predicted α-stable parameters and the location-scale property are used to linearly transform the intensity values ...
