Judul | : | PERBANDINGAN ESTIMASI S (SCALE) DAN ESTIMASI MM (METHOD OF MOMENT) PADA MODEL REGRESI ROBUST DENGAN DATA PENCILAN | |||
Abstrak | : | Regression model is a model used to describe the relationship between dependent and independent variables. One method that is often used to estimate the parameters of a regression model is the OLS (Ordinary Least Square) method. In the regression model it is possible that there are outliers that cause some of the regression assumptions are violated so that the predicted value becomes inaccurate. There is method that can handle outlier can be used. One of them is the robust regression method using estimations S (Scale) and MM (Method of Moment). Those methods has a high breakpointthat is maximum amount of outliers data that can be tolerated by a model. This study aims to apply and compare OLS estimates, S estimates and MM estimates that contain outliers data. The data used are secondary data in the form of the ability to read a group of children aged 4 to 7 years, age, memory scores and IQ. The results showed the S estimation robust regression method is the best method compared to OLS estimation and MM estimation because it has the highest R2 value of 94.29%. Based on the S estimation method obtained by the model Y = -1,107 + 0,484X_1 + 0.052X_2 + 0.045X_3 where Y is the reading score of children aged 4 to 7 years, X1 is age, X2 is the memory score and X3 is IQ. |
