The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.7 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.9 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.5 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.0007 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.5 SJR: 0.584 SNIP: 0.676 CiteScore™:: 3 H-Index: 25

ABSTRAKT

Bayesian identification has attracted considerable interest in various research areas for the determination of the mathematical model with suitable complexity based on input-output measurements. Regression analysis is an important tool in which Bayesian inference and Bayesian model selection have been applied. However, it has been noted that there is a subjectivity problem of model selection results due to the assignment of the prior distribution of the regression coefficients. Since regression coefficients are not physical parameters, assignment of their prior distribution is nontrivial. To resolve this problem, we propose a novel nonparametric regression method using Bayesian model selection in conjunction with general regression. In order to achieve this goal, we also reformulate the general regression under the Bayesian framework. There are two attractive features of the proposed method. First, it eliminates the subjectivity of model selection results due to the prior distribution of the regression coefficients. Second, the number of model candidates is drastically reduced, compared with traditional regression using the same number of design/input variables. Therefore, this allows for the consideration of a much larger number of potential design variables. The proposed method will be assessed and validated through two simulated examples and two real applications.
