We identify the temporary and permanent components of US stock prices through appropriate restrictions on a vector autoregression of real stock returns and changes in interest rates, employing alternative robust estimation procedures designed to allow for non-Gaussian innovations.  2000 Elsevier Science S.A.

In this short preliminary note I apply the methodology of gametheoretic probability to calculating non-asymptotic confidence intervals for the coefficient of a simple first order scalar autoregressive model. The most distinctive feature of the proposed procedure is that with high probability it produces confidence intervals that always cover the true parameter value when applied sequentially.

A scalar p-th order autoregression (AR(p)) is considered with heteroskedasticity of unknown form delivered by a smooth transition function of time. A limit theory is developed and three heteroskedasticity-robust tests statistics are proposed for inference, one of which is based on the nonparametric estimation of the variance function. The performance of the resulting testing procedures in finit...

BACKGROUND Internationally, the majority of out-of-hospital cardiac arrests where resuscitation is attempted (OHCAs) occur in private residential locations i.e. at home. The prospect of survival for this patient group is universally dismal. Understanding of the area-level factors that affect the incidence of OHCA at home may help national health planners when implementing community resuscitatio...
