Test for Infinite Variance in Stock Returns [PDF]
, 2008 The existence of second order moment or the finite variance is a commonly used assumption in financial time series analysis. We examine the validation of this condition for main stock index return series by applying the extreme value theory.

The size distribution of innovations revisited: an application of extreme value statistics to citation and value measures of patent significance [PDF]
This paper focuses on the analysis of size distributions of innovations, which are known to be highly skewed. We use patent citations as one indicator of innovation significance, constructing two large datasets from the European and US Patent Offices at ...

Spinal Involvement in Charge Syndrome: Implications for Management
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT CHARGE syndrome (OMIM #214800) is an autosomal dominant disorder caused by mutations in the CHD7 gene in most cases. Although originally defined by the CHARGE acronym (coloboma, heart defects, choanal atresia, growth restriction, genital hypoplasia, and ear anomalies), the recognized phenotype has expanded considerably to include highly ...

Extreme Value Theory Approach to Simultaneous Monitoring and Thresholding of Multiple Risk Indicators [PDF]
Risk assessments often encounter extreme settings with very few or no occurrences in reality.Inferences about risk indicators in such settings face the problem of insufficient data.Extreme value theory is particularly well suited for handling this type ...

American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Turner syndrome (TS) is associated with thoracic aortopathy and increased risk for aortic dissection, yet the natural history of aortic dilation is not well understood. We performed a retrospective longitudinal study of individuals with TS who participated in the TS Society of the United States Healthy Heart Project between 2003 and 2023 ...

Frontier Estimation and Extreme Values Theory [PDF]
In this paper we investigate the problem of nonparametric monotone frontier estimation from an extreme-values theory perspective. This allows to revisit the asymptotic theory of the popular Free Disposal Hull estimator in a general setup, to derive new ...

The Anatomical Record, EarlyView.Abstract The crania of leporid lagomorphs are uniquely fenestrated, including the posterior cranial bones and the lateral portion of the maxilla. The functional significance of the highly fenestrated rostrum has received considerably little attention, despite being absent in other mammalian herbivores with a long rostrum.
