This paper adopts a unified approach to the derivation of the asymptotic distributions of various seasonal unit root tests. The procedures considered are those of Dickey et al. [DHF], Kunst, Hylleberg et al. [HEGY], Osborn et al. [OCSB], Ghysels et al. [GHL] and Franses. This unified approach...

This paper uses Monte Carlo simulations to analyze the performance of several seasonal unit root tests for monthly time series. The tests are those of Dickey, Hasza and Fuller (DHF), Hylleberg, Engle, Granger and Yoo (HEGY), and Osborn, Chui, Smith and Birchenhall (OCSB). The unit root test of...

This paper presents a detailed discussion of the characteristics of seasonal integrated and near integrated processes, as well as the asymptotic properties of seasonal unit root tests. More specifically, the characteristics of a seasonal random walk and a more general seasonal integrated ARMA...

In this note we provide justification for some Monte Carlo results presented by Elder and Kennedy (2001). In particular we show that the severe size distortions observed by Elder and Kennedy are due to the presence of nuisance parameters in the data generation process, but ignored in the test...

<title>Abstract</title>The intangibility of banking services makes the evaluation of service quality and customer convenience difficult to measure. This paper aims to construct an integrated evaluation system for retail banking service quality and convenience at the bank branch level by combining cognitive...

<title>ABSTRACT</title> Remarkable progress has occurred over the years in the performance evaluation of bank branches. Even though financial measures are usually considered the most important in assessing branch viability, we posit that insufficient attention has been given to other factors that affect the...
