the strategy of model building in population biology
A descriptive survey of published population pharmacokinetic and/or pharmacodynamic (PK/PD) analyses from 2002 to 2004 was conducted and an evaluation made of how model building was performed and reported. (Dec., 1993), pp. combinations model building strategy with two ad hoc strategies and with truth, as well as considering the results of model averaging. In this article, Levins confronted some of the deepest philosophical issues surrounding modeling and theory construction. A Critical Assessment of Levins's The Strategy of Model Building in Population Biology (1966) Steven Hecht Orzack; Elliott Sober The Quarterly Review of Biology, Vol. Methods. Modeling, like inquiry more generally, is not a single method, but rather a complex suite of strategies. This paper is an interpretation and defense of Richard Levins’ “The Strategy of Model Building in Population Biology,” which has been extremely influential among biologists since its publication 40 years ago.

Strategies of Model Building in Population Genetics Anya Plutynski†‡ In 1966, Richard Levins argued that there are different strategies in model building in population biology. Levins also had written on philosophical issues in biology and modelling.One of his influential articles is "The Strategy of Model Building in Population Biology". 4. We found that model selection strat-egy had little effect on parameter estimator bias and pre-cision and that model averaging did improve bias and precision slightly. Philosophers of biology, citing the diverse aims, interests, and disciplinary cultures of biologists, argue that modeling is best understood in the context of its epistemic aims and cognitive payoffs. We selected 324 articles in Pubmed using defined keywords. Richard Levins's 1966 article ''The strategy of model building in population biology'' is an extremely influential analysis of the nature of scientific model building. 68, No. In terms of variable selection (i.e., He has influenced a number of contemporary philosophers of biology. 68, No. 533-546. A Critical Assessment of Levins's The Strategy of Model Building in Population Biology (1966) Steven Hecht Orzack; Elliott Sober The Quarterly Review of Biology, Vol. 4. A critical assessment of Levins's The strategy of model building in population biology (1966) In 1966, Richard Levins argued that there are different strategies in model building in population biology. The Semantics of Modeling?To recap, Levins claims that model building in population biology involves a necessary trade-off among modeling desiderata (1993,533).Since no model of any use can continually maximize all of these properties, we must settle for Type I, Type II, and Type III models. In this paper, I reply to Orzack and Sober’s (1993) critiques of Levins and argue that his views on modeling strategies apply also in the context of evolutionary genetics. In 1966, Richard Levins argued that there are different strategies in model building in population biology.
