Method for Outlier Detection

It allows you to choose the outlier detection method.

Available options are:

Remove Outliers from Output Data

It allows you to choose the option to remove outliers from the dataset.

Available options are:

  • No – Do not remove outliers.
  • Both sides – Remove outliers on both upper as well as lower side.
  • Only lower – Remove outliers only from the lower side.
  • Only upper – Remove outliers only from the upper side.

Outliers to be Treated

It allows you to choose the option to treat the outliers with a method of your choice.

Available options are:

  • Both sides – Treat outliers on both sides.
  • Only lower – Treat only lower side outliers.
  • Only upper – Treat only upper side outliers.
  • No – Do not treat the outliers. Leave them as is.
