N2 - To facilitate the regression analysis of the relationship between an outcome and explanatory variables in medical decision making, it is common practice to convert a continuous variable into one or more indicator variables. However, because of many uncertainties contained in medical data, linear regression models with indicator variables need modifying in order to include fuzziness. Previous studies on fuzzy linear regression analysis introduce fuzziness in the estimating models via fuzzy regression coefficients, In this study fuzziness is via the fuzzy membership functions replacing the model's indicator variables. As a result, the proposed approach does not have the common problems appearing in the usual fuzzy linear regression models.
