Comment on van der Linden article

A comment on van der Vorst et al. (2010).

The article was presented as a refutation of the idea that parents should model moderate/mealtime drinking for their adolescent offspring (as by permitting the adolescent a few sips of an alcoholic b...

Baer Invariants in Semi-abelian Categories I: General Theory T. Everaert and T. Van Der Linden

Extending the work of Fröhlich, Lue and Furtado-Coelho, we consider the theory of Baer invariants in the context of semi-abelian categories. Several exact sequences, relative to a subfunctor of the identity functor, are obtained. We consider a notion of commutator which, in the case of abelianization, corresponds to Smith’s. The resulting notion of centrality fits into Janelidze and Kelly’s the...

In principle, of course, missing data are just that—missing—and cannot be reconstructed after the fact. On the other hand, if covariates are available and the censoring mechanism can suc...
