The J-2X engine will power the upper stages of the Ares I and Ares V rockets.

A NASA-funded survey set to begin in 2008 could dramatically increase the number of known planets outside our solar system.

Astronauts are using a Star Trek tricorder-like device to keep track of microscopic life forms onboard the International Space Station.

A simultaneous confidence band provides useful information on the plausible range of the unknown regression model. Construction of a simultaneous confidence band has a history going back to Working and Hotelling (1929) and is often a hard problem when the

When the aim of an experiment is the estimation of a Generalised Linear Model (GLM), standard designsfrom linear model theory may prove inadequate. This paper describes a flexible approach for findingdesigns for experiments to estimate GLMs through the use of

The Gini coefficient has proved valuable as a measure of income inequality. In cross-sectional studies of the Gini coefficient, information about the accuracy of its estimate is crucial. We show how to use jackknife and linearization to estimate the variance
