Realized beta : persistence and predictability [PDF]

open access: yes, 2003
A large literature over several decades reveals both extensive concern with the question of time-varying betas and an emerging consensus that betas are in fact time-varying, leading to the prominence of the conditional CAPM.

How Does the Volatility of Volatility Depend on Volatility?

open access: yesRisks, 2020
We investigate the state dependence of the variance of the instantaneous variance of the S&P 500 index empirically. Time-series analysis of realized variance over a 20-year period shows strong evidence of an elasticity of variance of the variance ...

Using the realized relationship matrix to disentangle confounding factors for the estimation of genetic variance components of complex traits

open access: yesGenetics Selection Evolution, 2010
Background In the analysis of complex traits, genetic effects can be confounded with non-genetic effects, especially when using full-sib families. Dominance and epistatic effects are typically confounded with additive genetic and non-genetic effects ...

A Stochastic Volatility Model With Realized Measures for Option Pricing [PDF]

open access: yes, 2019
Based on the fact that realized measures of volatility are affected by measurement errors, we introduce a new family of discrete-time stochastic volatility models having two measurement equations relating both observed returns and realized measures to ...

Improving Markov switching models using realized variance [PDF]

open access: yesJournal of Applied Econometrics, 2017
SummaryThis paper proposes a class of models that jointly model returns and ex post variance measures under a Markov switching framework. Both univariate and multivariate return versions of the model are introduced. Estimation can be conducted under a fixed dimension state space or an infinite one.

Term structure of interest rates with short-run and long-run risks

open access: yesJournal of Finance and Data Science, 2022
We find that interest rate variance risk premium (IRVRP) — the difference between implied and realized variances of interest rates — is a strong predictor of U.S.

A new approach to determine batch size for the batch method in the Monte Carlo Eigenvalue calculation

open access: yesNuclear Engineering and Technology, 2019
It is well known that the variance of tally is biased in a Monte Carlo calculation based on the power iteration method. Several studies have been conducted to estimate the real variance.
