Abstract: Suppose Y is a response variable, possibly multivariate, with a density function f(y|x, v;β) conditional on the covariates (x, v) where x and v are vectors and β is a vector of unknown parameters. The authors consider the problem of estimating β when data on the covariate vector v are available for all observations while data on the covariate x are missing at random. They compare seve...

Between 1982 and 1988 a growth study was carried out at the Division of Pediatric Oncology of the University Hospital of Groningen. A special feature of the project was that sample sizes are small and that ages at entry may be very different. In addition the intended design was not fully complied with. This paper highlights some aspects of the statistical analysis which is based on (1) referenc...

Archibald and Knopfmacher recently considered the largest missing value in a composition of an integer and established the mean and variance. Our alternative, probabilistic approach produces (in principle) all moments in an almost automatic way. In order to show that our forms match the ones given by Archibald and Knopfmacher, we have to derive some identities which are interesting on their own...

In this paper we investigate the structure and motion problem for calibrated one-dimensional projections of a two-dimensional environment. In a previous paper the structure and motion problem for all cases with non-missing data was classified and solved. Our aim is here to classify all structure and motion problems, even those with missing data, and to solve them. Although our focus here is on ...
