Predictive Quantile Regression with Persistent Covariates: IVX-QR Approach
نویسنده
چکیده
This paper develops econometric methods for inference and prediction in quantile regression (QR) allowing for persistent predictors. Conventional QR econometric techniques lose their validity when predictors are highly persistent. I adopt and extend a methodology called IVX ltering (Magdalinos and Phillips, 2009) that is designed to handle predictor variables with various degrees of persistence. The proposed IVX-QR methods correct the distortion arising from persistent multivariate predictors while preserving discriminatory power. Simulations con rm that IVX-QR methods inherit the robust properties of QR. These methods are employed to examine the predictability of US stock returns at various quantile levels. Keywords: IVX ltering, Local to unity, Multivariate predictors, Predictive regression, Quantile regression. JEL classi cation: C22

Semi-parametric Quantile Regression for Analysing Continuous Longitudinal Responses
Recently, quantile regression (QR) models are often applied for longitudinal data analysis. When the distribution of responses seems to be skew and asymmetric due to outliers and heavy-tails, QR models may work suitably. In this paper, a semi-parametric quantile regression model is developed for analysing continuous longitudinal responses. The error term's distribution is assumed to be Asymmetr...
متن کاملConditional Quantile Processes Based on Series or Many Regressors
Quantile regression (QR) is a principal regression method for analyzing the impact of covariates on outcomes. The impact is described by the conditional quantile function and its functionals. In this paper we develop the nonparametric QR series framework, covering many regressors as a special case, for performing inference on the entire conditional quantile function and its linear functionals. ...
متن کاملEfficiency Bounds for Semiparametric Estimation of Quantile Regression under Misspecification
Allowing for misspecification in the linear conditional quantile function (CQF), we calculate the semiparametric efficiency bound for the solution to the population quantile regression (QR) problem or the best linear predictor for a response variable under the asymmetric check loss function. The pseudo-true QR parameter that solves a non-differentiable unconditional moment restriction is interp...

Quantile regression (QR) fits a linear model for conditional quantiles, just as ordinary least squares (OLS) fits a linear model for conditional means. An attractive feature of OLS is that it gives the minimum mean square error linear approximation to the conditional expectation function even when the linear model is misspecified. Empirical research using quantile regression with discrete covar...
متن کاملQuantile regression in environmental health: Early life lead exposure and end-of-grade exams.
Conditional means regression, including ordinary least squares (OLS), provides an incomplete picture of exposure-response relationships particularly if the primary interest resides in the tail ends of the distribution of the outcome. Quantile regression (QR) offers an alternative methodological approach in which the influence of independent covariates on the outcome can be specified at any loca...
