چکیده

We conducted a sensitivity analysis of the results of weighted voting experiments by varying two features of the experimental protocol by Montero et al. (2008): (1) the way in which the roles of subjects are reassigned in each round (random role versus fixed role) and (2) the number of proposals that subjects can simultaneously approve (multiple approval versus single approval). It was observed that the differences in these protocols had impacts on the relative frequencies of minimum winning coalitions as well as how negotiations proceed. 3-player MWCs were more frequently observed, negotiations were much longer, subjects made less mistakes, and proposal-objection dynamics were more frequently observed, under the protocol with fixed role and single approval than under the protocol with random role and multiple approval. JEL Classification Numbers: C71, C92, D72

Feature Selection and Classification of Microarray Gene Expression Data of Ovarian Carcinoma Patients using Weighted Voting Support Vector Machine

We can reach by DNA microarray gene expression to such wealth of information with thousands of variables (genes). Analysis of this information can show genetic reasons of disease and tumor differences. In this study we try to reduce high-dimensional data by statistical method to select valuable genes with high impact as biomarkers and then classify ovarian tumor based on gene expression data of...
