Factorial Experiment with Fuzzy and Statistical Techniques
نویسنده
چکیده
Where fuzzy regression can be applied and, in which conditions fuzzy regression method more appropriate tool for the investigations are identified in this paper. The contrast between fuzzy regression and ordinary regression analysis and three approach of fuzzy regression are summarized. In this paper, we estimated the values of the parameters in the factorial experiment in the textile industry by applying possibilistic regression analysis. When the data are made to approach a crisp state in fuzzy regression analysis, the results of fuzzy regression should approach the results of ordinary regression. Using linear programming, we constructed fuzzy regression model that is equal to the statistical least-square regression model. Key-Words: fuzzy regression, vagueness, fuzziness, randomness, insufficient data, assumptions, factorial design.

متن کاملDeveloping Fuzzy Models for Estimating the Quality of VoIP
This paper presents a novel method for modeling the one-way quality prediction of VoIP, non-intrusively. Intrusive measures of voice quality suffer from common deficiency that is the need of reference signal for evaluating the quality of voice. Owing to this lack, a great deal of effort has been recently devoted for modeling voice quality prediction non-intrusively according to quality degradat...
متن کاملFitting Second-order Models to Mixed Two-level and Four-level Factorial Designs: Is There an Easier Procedure?
Fitting response surface models is usually carried out using statistical packages to solve complicated equations in order to produce the estimates of the model coefficients. This paper proposes a new procedure for fitting response surface models to mixed two-level and four-level factorial designs. New and easier formulae are suggested to calculate the linear, quadratic and the interaction coeff...
