Simple means to improve the interpretability of regression coefficients
Summary 1. Linear regression models are an important statistical tool in evolutionary and ecological studies. Unfortunately, these models often yield some uninterpretable estima...
Estimating Time Varying Risk Premia in the Term Structure: The Arch-M Model
The expectati on of the excess holding yield on a long bond is postulated to depend upon its conditional variance. Engle's ARCH model is extended to allow the conditional varian...
Caltech-256 Object Category Dataset
We introduce a challenging set of 256 object categories containing a total of 30607 images. The original Caltech-101 [1] was collected by choosing a set of object categories, do...
Climate Change and Food Systems
Food systems contribute 19%–29% of global anthropogenic greenhouse gas (GHG) emissions, releasing 9,800–16,900 megatonnes of carbon dioxide equivalent (MtCO 2 e) in 2008. Agricu...
Item-based top-<i>N</i>recommendation algorithms
The explosive growth of the world-wide-web and the emergence of e-commerce has led to the development of recommender systems ---a personalized information filtering technology u...
Semiparametric Difference-in-Differences Estimators
The difference-in-differences (DID) estimator is one of the most popular tools for applied research in economics to evaluate the effects of public interventions and other treatm...
Inorganic Materials as Catalysts for Photochemical Splitting of Water
Photochemical splitting of water into H2 and O2 using solar energy is a process of great economic and environmental interest. Since the discovery of the first water splitting sy...
An Intertemporal General Equilibrium Model of Asset Prices
This paper develops a continuous time general equilibrium model of a simple but complete economy and uses it to examine the behavior of asset prices. In this model, asset prices...
The epithelial–mesenchymal transition: new insights in signaling, development, and disease
The conversion of an epithelial cell to a mesenchymal cell is critical to metazoan embryogenesis and a defining structural feature of organ development. Current interest in this...
College sophomores in the laboratory: Influences of a narrow data base on social psychology's view of human nature.
For the 2 decades prior to 1960, published research in social psychology was based on a wide variety of subjects and research sites. Content analyses show that since then such r...
