OBJECTIVE We investigated associations between changes in national food energy supply and in average population body weight. METHODS We collected data from 24 high-, 27 middle- and 18 low-income countries on the average measured body weight from global databases, national health and nutrition survey reports and peer-reviewed papers. Changes in average body weight were derived from study pairs...

Most of us know less about statistics than we feel we should but, even as a scientist, it’s often not necessary to be an expert. When it comes to presenting your data, or reviewing someone else’s, however, it can help to have a ready reference at your fingertips. Before you run out and buy a textbook or ask advice from a colleague, take a look at what the web has to offer. Sites offering online...

A white paper on analyzing data from statistically designed experiments in industry, business and research using the IMSL™ C Numerical Library.

this was a study to investigate quantitative and qualitative characteristics of fiber extracted from crossbred goats derived from female hair goats indigenous of qom and male cashmere goats of south of khorasan. from a total of 75 indigenous and cross goats aged 1-3, qualities such as the percentage of cashmere in fleece, percentage of hair in fleece, hair staple length, cashmere staple length,...

Currently there are many theories about quality education. The paper presents some of them. It also includes points Deming’s philosophy and statistical indicators implemented to determine lecturers’ achievements in Russian higher shows that these do not align with Deming's goals, according both educational theories. A new system measurements should thus be developed. This based upon ideas the d...

Abstract We develop a possibility of generating tensor non-Gaussianity in kind anisotropic inflation, where (1) gauge field is kinetically coupled to spectator scalar field. Owing this coupling, the coherent mode electric appears and softly breaks isotropy Universe. compute bispectrum linearly-polarized perturbations sourced by find that it strongly red-tilted has distinctive statistical anisot...
