Estimation of tail thickness parameters from GJR-GARCH models [PDF]

open access: yes, 2009
We propose a method of estimating the Pareto tail thickness parameter of the unconditional distribution of a financial time series by exploiting the implications of a GJR-GARCH volatility model. The method is based on some recent work on the extremes of GARCH-type processes and extends the method proposed by Berkes, Horváth and Kokoszka (2003). We show

open access: yesACR Open Rheumatology, Volume 8, Issue 4, April 2026.
Objective The RNA‐binding region‐containing protein 3 (RNPC3) protein acts as a molecular bridge, promoting U11/U12 RNP complex formation. In previous reports, patients with systemic sclerosis (SSc) with anti‐RNPC3 autoantibodies had an increased risk of interstitial lung disease (ILD), severe gastrointestinal (GI) disease, and cancer.
