Data Science Tip Day #8 - Dealing with Skewness for Error histograms after Linear Regression

In previous posts we have seen histogram based validation for errors. When a left / right skew based distribution is observed some transformation techniques to apply are
  • Right Skewed - Apply Log
  • Slightly Right - Square root
  • Left Skewed - Exponential
  • Slightly Left - Square root, Cube
Happy Learning!!!
