A)If the value of r²increases as more variables are added to the model,the variables should remain in the model,regardless of the magnitude of increase. B)If the value of the adjusted r²increases as more variables are added to the model,the variables should remain in the model. C)If the value of r²increases as more variables are added to the model,the variables should not remain in the model,regardless of the magnitude of the increase. D)If the value of the adjusted r²increases as more variables are added to the model,the variables should not remain in the model. E)None of the statements provide accurate guidance.

The adjusted r-squared value takes into account the number of variables in the model, providing a better indication of whether additional variables are improving the model or not. Therefore, if the adjusted r-squared value increases as more variables are added to the model, the variables should remain in the model.
