Motivated by an example in nutritional epidemiology, we investigate some design and analysis aspects of linear measurement error models with missing surrogate data. The specific problem investigated consists of an initial large sample in which the response (a food frequency questionnaire, FFQ)...

A language of a statistical system is important, even though it bas an effective graphical user interface. A language may be used to control the statistical system at will and to implement new statistical procedures which are not realized in the system at the beginning. This paper introduces the...

MM*STAT is a HTML-based and flexibly applicable computer tool for supporting teaching and learning statistics in introductory courses via the internet or from a CD. It can be used in class rooms or for reviewing the lecture subjects by the students on their own. The main elements of MM*STAT are:...

We propose a client server architecture for statistical computing. The main feature of our approach is the possibility to connect various client programs via a TCP/IP connection to a powerful statistical engine. This offers the opportunity to include the statistical engine into a number of...

We consider an additive model with second order interaction terms. It is shown how the components of this model can be estimated using marginal integration, and the asymptotic distribution of the estimators is derived. Moreover, two test statistics for testing the presence of interactions are...
