Contributions to Theil-Sen Regression Analysis Parameter Estimation with Weighted Median

Regression analysis is one of the most commonly used estimation methods. In statistical studies, some assumptions must be fully met to make good estimations with regression analysis. Some these are not always fulfilled in real life data. For such cases, alternative methods used. One them Theil-sen method, which non-parametric techniques. this study, different techniques were proposed by using weighted median parameter instead Theil-Sen method. With four algorithms, new approaches have been introduced. It has seen that obtained results successful compared classical results.
