We introduce a goodness of fit process for quantile regression analogous to the conventional R2 statistic of least squares regression. Several related inference processes designed to test composite hypothese about the combined effect of several covariates over an entire range of conditional...

This paper proposes a multidimensional procedure for jointly assessing the absolute and relative pro-poorness of growth. It is also a procedure for testing whether poverty comparisons can be made over classes of indices that incorporate both absolute and relative views of poverty. Besides being...

This Test Guideline is designed to assess the toxicity of substances to freshwater aquatic plants of the genus Lemna (duckweed). Exponentially growing plant cultures of the genus Lemna (Lemna gibba and Lemna minor usually) are allowed to grow as monocultures in, at least, five concentrations of...
