Abstract: | The purpose of this paper is to discuss the problem for least squares fitting of fuzzy-valued data, which are expressed as fuzzy numbers, and to develop an S-shaped curve regression model for fitting this type of data. It is shown that the solution of the S-curve regression model is equivalent to the solution of the corresponding linear equations, and, furthermore, the solution can be explicitly obtained by solving the linear equations. |
