Background: Longitudinal data often have multiple (repeated) measures recorded along a time trajectory. For example, the two cohorts from the Framingham Heart Study (GAW13 Problem 1) contain 21 and 5 repeated measures for hypertension phenotypes as well as epidemiological risk factors, respectively. Direct modelling of a large number of serially and biologically correlated traits in the context...

Abstract This paper describes a method for measuring the longitudinal wake potential of the Cornell Electron-Positron Storage Ring (CESR). The longitudinal wake potential was determined by measuring the time delay between successive bunches as a function of current. The slope of the wake potential was determined by the changes in the bunch length as a function of bunch current. A theoretical de...

Conducting survey interviews on the internet has become an attractive method for lowering data collection costs and increasing the frequency of interviewing, especially in longitudinal studies. However, the advantages of the web mode for studies with frequent re-interviews can be offset by the serious disadvantage of low response rates and the potential for nonresponse bias to mislead investiga...
