We consider cointegration tests in the situation where the cointegration rank is deficient. This situation is of … interest in finite sample analysis and in relation to recent work on identification robust cointegration inference. We derive … asymptotic theory for tests for cointegration rank and for hypotheses on the cointegrating vectors. The limiting distributions …

Rank-based estimators are important tools of robust estimation in popular semiparametric models under monotonicity constraints. Here we study weighted versions of such estimators. Optimally weighted monotone rank estimator (MR) of Cavanagh and Sherman (1998) attains the semiparametric efficiency...

Ridder and Woutersen (2003) have shown that under a weak condition on the baseline hazard there exist root-N consistent estimators of the parameters in a semiparametric Mixed Proportional Hazard model with a parametric baseline hazard and unspecified distribution of the unobserved heterogeneity....

In a recent paper Speckman et al. (2002) introduced a technique for accounting co-variates when their effects are nonlinear. They proposed a test for a one-sided analysis of covariance which is based on a rank test for the residuals obtained by smoothing the dependent variable on the covariate....
