WebPoint 1 of Assumption 2 requires that units’ treatments do not vary within each (g;t) cell, a situation we refer to as a sharp design. This is for instance satisﬁed when the treatment is a group-level variable, for instance a county- or a state-law. This is also mechanically satisﬁed when N g;t = 1 for all (g;t). WebHomogenization implies that the distribution of elements in your sample is not uniform, so you heat it to increase diffusivity. Solutionization implies that you have some precipitates, so you heat it to make those precipitates dissolve. Note that the presence of precipitates probably means the elements are not uniformly distributed in your sample.

WebIn a block design, experimental subjects are first divided into homogeneous blocks before they are randomly assigned to a treatment group. If, for instance, an experimenter had reason to believe that age might be a significant factor in the effect of a given medication, he might choose to first divide the experimental subjects into age groups, such as under 30 … Web(Note: by "homogeneity", I assume you mean "homogeneity of variance".) They are, in essence, two different names for the same assumption, which might be called in more colloquial English "constant variance of the errors" (of course, in practice we do not have access to the true errors, only the residuals, which are what we actually check). ineos chocolate bayou expansion
