TAIL DEPENDENCE OF OLS [PDF]

open access: yesEconometric Theory, 2021
This paper shows that if the errors in a multiple regression model are heavy-tailed, the ordinary least squares (OLS) estimators for the regression coefficients are tail-dependent. The tail dependence arises, because the OLS estimators are stochastic linear combinations of heavy-tailed random variables. Moreover, tail dependence also exists between the

The Optical Effects of Capping Layers on the Performance of Transparent Organic Light-Emitting Diodes

open access: yesIEEE Photonics Journal, 2012
In transparent organic light-emitting diodes (TOLEDs), the asymmetry in the optical paths causes difference between the bottom and top emitting lights, both in emissions and spectral distributions.
