Philosophy of Science Philosophy philosophy philosophy of cosmology philosophy of science AIC cosmological modeling model selection Contemporary cosmology is teeming with model underdetermination and cosmologists are looking for methods with which to relieve some of this underdetermination. One such method that has found its way into cosmology in recent years is the <i>Akaike Information Criterion (AIC)</i>. The criterion is meant to select the model that loses the least amount of information in its approximation of the data, and furthermore <i>AIC</i> shows a preference for simplicity by containing a penalty term that penalizes models with excessive complexity. The principle aim of this paper is to investigate some of the strengths and weaknesses of <i>AIC</i> against two philosophical backdrops in order to determine its usefulness in cosmological model selection. The backdrops or positions against which <i>AIC</i> will be assessed are I) realist and II) antirealist. It will be argued that on both of these positions there is at least one feature of <i>AIC</i> that proves problematic for the satisfaction of the aims of the position. 2015-09-17 English text Ohio University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1430478203 http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1430478203 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
