Asymptotically Optimal Smoothing with Arch Models [PDF]

open access: yesEconometrica, 1996
Summary: Suppose an observed time series is generated by a stochastic volatility model -- i.e., there is an unobservable state variable controlling the volatility of the innovations in the series. As shown by the author [J. Econom. 52, No. 1/2, 61-90 (1992; Zbl 0761.62169)], and the author and \textit{D. P. Foster} [Econometrica 62, No.

Parsimonious Heterogeneous ARCH Models for High Frequency Modeling [PDF]

open access: yesJournal of Risk and Financial Management, 2020
In this work we study a variant of the GARCH model when we consider the arrival of heterogeneous information in high-frequency data. This model is known as HARCH(n). We modify the HARCH(n) model when taking into consideration some market components that we consider important to the modeling process.

LINC01116, a hypoxia‐lncRNA marker of pathological lymphangiogenesis and poor prognosis in lung adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
The LINC01116 long noncoding RNA is induced by hypoxia and associated with poor prognosis and high recurrence rates in two cohorts of lung adenocarcinoma patients. Here, we demonstrate that besides its expression in cancer cells, LINC01116 is markedly expressed in lymphatic endothelial cells of the tumor stroma in which it participates in hypoxia ...
