More About Molecular Genetics In 1992 the American Association for the Advancement of Science conducted an opinion poll of members, asking what scientific specialty holds the greatest promise over the next decade. “Genetics” or “molecular and cell biology,” or both, were listed most often by biologists, medical scientists, social/ behavioral scientists, chemists, and physicists/astronomers— even more often than their own specialties.

Francis S. Collins Despite the best efforts of the American Scientific Affiliation to bridge the gap between science and faith, few gatherings of scientists involved in biology include any meaningful discussion about the spiritual significance of the current revolution in genetics and genomics. Most biologists and geneticists seem to have concluded that science and faith are incompatible, but few who embrace that conclusion seem to have Continue to download »

Abstract Latent class models are used for cluster analysis of categorical data. Underlying such a model is the assumption that the observed variables are mutually independent given the class variable. A serious problem with the use of latent class models, known as local dependence, is that this assumption is often untrue. In this paper we propose hierarchical latent class models as a framework where the local dependence problem Continue to download »
