Lopsided Reasoning on Lopsided Tests and Multiple Comparisons
For those who have not recognized the disparate natures of tests of statistical hypotheses and tests of scientific hypotheses, one-tailed statistical tests of null hypotheses such as ∂ ≤ 0 or ∂ ≥ 0 have often seemed a reasonable procedure. We earlier reviewed the many grounds for not regarding them as such. To have at least some power for detection of effects in the unpredicted direction, sever...
متن کاملLopsided Approximation of Amoebas
The amoeba of a Laurent polynomial is the image of the corresponding hypersurface under the coordinatewise log absolute value map. In this article, we demonstrate that a theoretical amoeba approximation method due to Purbhoo can be used efficiently in practice. To do this, we resolve the main bottleneck in Purbhoo’s method by exploiting relations between cyclic resultants. We use the same appro...
متن کاملLopsided Regional Economic Development
China has performed under its new inter-governmental Fiscal System (so called “tax-sharing system”) for about seven years since 1994. The main contents of the system are the reallocation of governmental responsibilities and sharing of taxes between the central and provincial level. Theoretically, one of the main purposes is to realize equalization of public service all over the country. In fact...
متن کاملCombinatorics of lopsided sets
We develop a theory of isometric subgraphs of hypercubes for which a certain inheritance of isometry plays a crucial role. It is well known that median graphs and closely related graphs embedded in hypercubes bear geometric features that involve realizations by solid cubical complexes or are expressed by Euler-type counting formulae for cubical faces. Such properties can also be established for...
متن کاملKinematically Lopsided Spiral Galaxies
Asymmetries in the distribution of light and neutral hydrogen are often observed in spiral galaxies. Here, attention is drawn to the presence of large-scale asymmetries in their kinematics. Two examples of kinematically lopsided galaxies are presented and discussed. The shape of the rotation curve –rising more steeply on one side of the galaxy than on the other– is the signature of the kinemati...
