Binary and Ordinal Random Effects Models Including Variable Selection [PDF]

, 2010
A likelihood-based boosting approach for fitting binary and ordinal mixed models is presented. In contrast to common procedures it can be used in high-dimensional settings where a large number of potentially influential explanatory variables is available.

A Study of Be Star Variability [PDF]

Symposium - International Astronomical Union, 1982
Variations of Balmer emission line strength for Be stars are compared to simultaneously measured photometric light-curves in the visual and infrared regions of the spectrum. Three different types of correlations between photometric and spectrometric variations are described. Variable intensity of continuous recombination radiation from ionized hydrogen
