In this article the results of Waddell and Azad (2009) are extended. In particular, the geometric percentage mean standard deviation measure of the fit of distances to a phylogenetic tree are adjusted for the number of parameters fitted on the tree. The formulae are also presented in their general form for any weight that is a function of the distance. The cell line gene expression data set of ...

Squares are experimental force versus extension data for 97 kb X-DNA dimers from figure 3 of (2); solid line is a fit of the entropic force required to extend a worm-like polymer. The fit parameters are the DNA length (L = 32.80 + 0.10 plm) and the persistence length (A = 53.4 ± 2.3 nm). Shown for comparison (dashed curve) is the freely jointed chain model (2) with L = 32.7 KILm and a segment l...

Combining results presented in two papers in this Monthly yields the following elementary result. Any line of best fit for the zeros of a polynomial is a line of best fit for its critical points. This note gives a generalization of results on cubic polynomials presented in [1]. Our notation will follow that paper. A line of best fit for a set of points in the plane is defined, as in [1, p. 682]...

The discrete multi-way layout is a widespread data-type associated with experimental designs, gene or protein chips, digital images or videos, and more. A discrete multi-way layout has a finite number of factor level combinations. The layout may be unbalanced or incomplete or both. We consider candidate fits to an incomplete layout that are least squares fits to certain submodels induced by ten...

WASHINGTON (AP) — Democrats promised Thursday to speed an economic recovery package through Congress, but vowed to rearrange President Bush’s budget proposal to ben­ efit m iddle-income Americans, not the rich. “ Democrats w ill not obstruct, but we w ill try to improve the p re s id e n t’s p acka ge ,” sa id House Majority Leader Richard Gephardt, D-Mo., as the Budget Committee began hearings...

This report investigates how neurons with complex dynamics, specifically adaptation, can be incorporated into the Neural Engineering Framework. The focus of the report is fitting a linear-nonlinear system model to an adapting neuron model using system identification techniques. By characterizing the neuron dynamics in this way, we hope to gain a better understanding of what sort of temporal bas...

Purpose This study aims to examine the role of an overall model fit assessment in context partial least squares path modeling (PLS-PM). In doing so, it will explain when is important assess and provides ways assessing composite models. Moreover, resolve major concerns about that have been raised literature on PLS-PM. Design/methodology/approach paper explains how PLS Furthermore, discusses PLS-...
