Breaking up is hard to do: the heartbreak of dichotomizing continuous data.
Researchers often take variables that are measured on a continuum and then break them into categories (for example, above or below some cut-point), either to place subjects into groups or as an outcome measure. In this article, we show that the rationales given for this practice are weak and that categorization results in lost information, reduced power of statistical tests, and increased proba...
متن کاملBreaking Up (Amyloid) Is Hard to Do
S tandard " Alzheimerology " lore holds that the insolubility of amyloid plaques and neurofi brillary tangles was a great impediment to elucidating the molecular composition of each of these structures. Roughly 77 years passed between Alois Alzheimer's description of the clinical and pathological features of the illness suffered by Auguste D. and the now classical reports from George Glenner, C...
متن کاملBreaking up is hard to do
The small GTPases RalA and RalB are activated downstream of oncogenic Ras. While activation of RalA is critically important for tumor initiation and growth of Ras-driven cancers, the highly similar small GTPase RalB is implicated in cell survival and metastasis. This difference in function between these two related proteins maps to the C-terminus, a 30 amino acid region that regulates subcellul...
متن کاملAnimal cytokinesis: Breaking up is hard to do
Recent studies have shed new light on how the physical association between sister cells is severed at the end of cytokinesis while the membrane is resealed. Comparisons with yeast suggest that daughter cell shape may feed back to regulate cytokinesis through the Bub2 checkpoint system.
متن کاملBreaking Up is Hard to Do: Blind Signal Separation
In \blind signal separation," a collection of linear combinations of signals is broken into its original sources without any knowledge of their initial characteristics. In this paper, we review four important yet fundamentally diierent approaches to this problem. An algorithm by Herault and Jutten emulates structures found in biological systems through a recursive adaptive neural network. In JA...
