Kunert and Utzig (1993) only give a rough upper bound for the worst-case variance bias. This may lead to overly conservative … tests. In this paper we derive an exact upper limit for the variance bias due to carry-over for an arbitrary number of …

We determine optimal crossover designs for the estimation of direct treatment effects in a model with mixed and self carryover effects. The model also assumes that the errors within each experimental unit are correlated following a stationary first-order autoregressive process. The paper...

sources of asymptotic bias of the LS estimator: bias due to correlation or heteroscedasticity of the idiosyncratic error term …, and bias due to predetermined (as opposed to strictly exogenous) regressors. A bias corrected least squares estimator is … provided. We also present bias corrected versions of the three classical test statistics (Wald, LR and LM test) and show that …
