| 1 | Therefore it is necessary to test the variance homogeneity of the models. | |
| 2 | In general, the T-S fuzzy system can be divided into homogeneous fuzzy systems and affine fuzzy systems. | |
| 3 | In this paper, we extend their result to nonlinear regression . | |
| 4 | If the variance is not homogeneous and unknown, the regression analysis will meet many questions. | |
| 5 | Meet the normal distribution and homogeneity of variance using the group analysis of variance design; |
