Exact optimal and adaptive inference in regression models under heteroskedasticity and non-normality of unknown forms [PDF]

open access: yes, 2008
In this paper, we derive simple point-optimal sign-based tests in the context of linear and nonlinear regression models with fixed regressors. These tests are exact, distribution-free, robust against heteroskedasticity of unknown form, and they may be ...
