• Hi everybody
    I have the model below. I found that I have one outlier that has influence on the coefficients. I do not want to drop the outlier. Is there any other way that I can modify the model without dropping the outlier?
  • As you see, I did robust but still it did not give me the coefficient close to ones when I dropped the outliers.
