We review the notion of time series linearity and describe recent advances in linearity and Gaussianity testing via data-resampling methodologies. Many advances have been made since the first published tests of linearity and Gaussianity by Subba Rao and Gabr in 1980, including several resampling-based proposals. This article is intended to be instructive in explaining and motivating linearity t...

Cassava leaves, which usually contain large quantities of cyanogenic glycosides, were processed into a Zairian traditional vegetable sauce "Mpondu" by simple methods which included blanching (10 min), mashing and then boiling for 20-80 min. These methods enhanced the detoxification of the leaves, with blanching alone resulting in the loss of 57% of the free (non-glycosidic) cyanide content and ...

Problems with teaching introductory courses in circuit analysis and design are well known and have been extensively documented over the past few decades. Inspired by a few of the researchers in the field, we have designed a collection of supplementary materials to be presented in our introductory courses. This material is designed specifically to teach students how to solve problems in a practi...

In December 1998, 15 percent of unemployed jobseekers, and 7 percent of employed persons used the internet to look for a new job. Conditioning on internet access from home, internet job search rates rise to 50 percent of unemployed jobseekers and 15 percent of the employed. Only 9 percent of black, and 7 percent of Hispanic unemployed jobseekers conduct on-line job search, compared to 16 percen...

This paper reviews some traditional and more recent methods for analyzing unreplicated experiments. Such experiments have presented a challenge to statisticians throughout their involvement in agricultural research. At Rothamsted this began in 1919, when R.A. Fisher was appointed to analyze the accumulated data from the classical field experiments. Fisher’s experiences with the classicals, whic...
