DOI: 10.1002/sim.8765
Abstract: In this article, we develop a so-called profile likelihood ratio test (PLRT) based on the estimated error density for the multiple linear regression model. Unlike the existing likelihood ratio test (LRT), our proposed PLRT does… read more here.

DOI: 10.1016/j.econlet.2018.07.030
Abstract: In this paper we investigate the bootstrap implementation of the likelihood ratio test for a unit root recently proposed by Jansson and Nielsen (2012). We demonstrate that the likelihood ratio test shows poor finite sample… read more here.

DOI: 10.1080/03610926.2016.1183785
Abstract: ABSTRACT The paper considers a significance test of regression variables in the high-dimensional linear regression model when the dimension of the regression variables p, together with the sample size n, tends to infinity. Under two… read more here.

DOI: 10.3390/e24121785
Abstract: The generalized likelihood ratio test (GLRT) for composite hypothesis testing problems is studied from a geometric perspective. An information-geometrical interpretation of the GLRT is proposed based on the geometry of curved exponential families. Two geometric… read more here.
