This study conducts Monte Carlo simulation exercises to determine the finite sample properties of the Fan-Li test [1996] when the interest focuses on uncovering the impact of omitted variables on the semiparametric partially linear model (PLM). It essentially subjects the said test to various...

In this study, we compare the performance of the Zheng (1996) and Elisson-Elisson (2000) tests for omitted variable problems in parametric regression models. The study finds that the Elisson and Elisson test has better finite sample performance relative to the Zheng test. The results also...

Consider a multivariate nonparametric model where the unknown vector of functions depends on two sets of explanatory variables. For a fixed level of one set of explanatory variables, we provide consistent statistical tests, called local rank tests, to determine whether the multivariate...
