We provide the asymptotic analy- sis of common volatility risk factor estimation using large panels of filtered volatilities such as (1) parametric spot volatility filters
We present the asymptotic properties of the proposed estimator in Section 3 and present the finite sample performance of our estimator via some numerical simulations both in the iid
(A simulation-based method for density estimation in the context of parametric time series mod- els with latent states is also considered in Zhao ( 2011 ). Zhao’s estimator requires
In the simulations, we consider globally invalid covariates and find that our average estimators perform reasonably well and sometimes even outperform the estimator based on
This article therefore studies the asymptotic behavior of panel unit root tests based on the Cauchy estimator in panels with unconditionally heteroscedastic innovations as
RELSE is de " ned as the ratio of the average estimated standard error using the appropriate asymptotic variance } covariance matrix of the respective estimator and the
Data were analyzed with LISREL 8.80 in the form of normality test and multicollinearity test and were continued with asymptotic covariance matrix estimation and
CONTRIBUTIONS OF THE PAPER The contributions of this paper can be summarized as fol- lows: • We propose a regularized sample covariance matrix estimator of the covariance matrix for
