Testing for the equality of integration orders of multiple series

Wang, Man; Chan, Ngai Hang - In: Econometrics : open access journal 4 (2016) 4, pp. 1-10

essential step in testing for (fractional) cointegration in the bivariate case. For the multivariate case, there are several … versions of cointegration, and the version given in Robinson and Yajima (2002) has received much attention. In this definition … integration order. Furthermore, this time series vector is said to be cointegrated if there exists a cointegration in any of the …

On the validity of tests for asymmetry in residual-based threshold cointegration models

Schild, Karl-Heinz; Schweikert, Karsten - In: Econometrics : open access journal 7 (2019) 1/12, pp. 1-13

finding sufficient evidence for cointegration in a first step. The extent of oversizing the test for long-run asymmetry … depends inversely on the power of the primary cointegration test. Hence, tests for long-run asymmetry become invalid in cases …

Frequency-domain evidence for climate change

Mangat, Manveer Kaur; Reschenhofer, Erhard - In: Econometrics : open access journal 8 (2020) 3/28, pp. 1-15

The goal of this paper is to search for conclusive evidence against the stationarity of the global air surface temperature, which is one of the most important indicators of climate change. For this purpose, possible long-range dependencies are investigated in the frequency-domain. Since...

Fixed and long time span jump tests : new Monte Carlo and empirical evidence

Cheng, Mingmian; Swanson, Norman R. - In: Econometrics : open access journal 7 (2019) 1/13, pp. 1-32

Numerous tests designed to detect realized jumps over a fixed time span have been proposed and extensively studied in the financial econometrics literature. These tests differ from “long time span tests” that detect jumps by examining the magnitude of the jump intensity parameter in the data...

A frequentist alternative to significance testing, p-values, and confidence intervals

Trafimow, David - In: Econometrics : open access journal 7 (2019) 2/26, pp. 1-14

There has been much debate about null hypothesis significance testing, p-values without null hypothesis significance testing, and confidence intervals. The first major section of the present article addresses some of the main reasons these procedures are problematic. The conclusion is that none...

Fractional unit root tests allowing for a structural change in trend under both the null and alternative hypotheses

Chang, Seong Yeon; Perron, Pierre - In: Econometrics : open access journal 5 (2017) 1, pp. 1-26

This paper considers testing procedures for the null hypothesis of a unit root process against the alternative of a fractional process, called a fractional unit root test. We extend the Lagrange Multiplier (LM) tests of Robinson (1994) and Tanaka (1999), which are locally best invariant and...

Goodness-of-fit tests for copulas of multivariate time series

Rémillard, Bruno - In: Econometrics : open access journal 5 (2017) 1, pp. 1-23

In this paper, we study the asymptotic behavior of the sequential empirical process and the sequential empirical copula process, both constructed from residuals of multivariate stochastic volatility models. Applications for the detection of structural changes and specification tests of the...

Har testing for spurious regression in trend

Phillips, Peter C. B.; Wang, XiaoHu; Zhang, Yonghui - In: Econometrics : open access journal 7 (2019) 4/50, pp. 1-28

The usual t test, the t test based on heteroskedasticity and autocorrelation consistent (HAC) covariance matrix estimators, and the heteroskedasticity and autocorrelation robust (HAR) test are three statistics that are widely used in applied econometric work. The use of these significance tests...
