R factors in Rietveld analysis: How good is good enough?
People mastering Rietveld refinement techniques commonly ask the same questions: What do the various Rietveld discrepancy values, i.e., goodness-of-fit, !2, and R factors mean? Also, which ones are most important? Finally, what values allow one to distinguish good refinements from poor ones? These questions are also important to people who review Rietveld results, as well as individuals trying ...
متن کاملGood triangulations yield good tours
Consider the following heuristic for planar Euclidean instances of the traveling salesman problem (TSP): select a subset of the edges which induces a planar graph, and solve either the TSP or its graphical relaxation on that graph. In this paper, we give several motivations for considering this heuristic, along with extensive computational results. It turns out that the Delaunay and greedy tria...
متن کاملHow good is good enough in path analysis of fMRI data?
This paper is concerned with the problem of evaluating goodness-of-fit of a path analytic model to an interregional correlation matrix derived from functional magnetic resonance imaging (fMRI) data. We argue that model evaluation based on testing the null hypothesis that the correlation matrix predicted by the model equals the population correlation matrix is problematic because P values are co...

متن کاملTranslating evidence into practice: how good is good enough?
The birth of the evidence-based medicine (EBM) movement in the early 1990s generated a greater interest in measuring the extent to which scientific knowledge was appropriately applied to therapeutic decisions. Investigators sought to challenge the widespread belief that only a minority of treatments provided to patients were based upon the best available scientific evidence. In 1995 Ellis and c...
