Please up vote for the same and thanks!!!

Do reach out in the comments for any queries

Answer:

The adjusted R^2 can be negative as it tends to penalize the regular R^2 if the choice of variables is incorrect. Other options including greater than and between 0 and 1 is false.

Hence Option C

  • Which of the following statements is false about the coefficient of determination r2

    Which of the following statements are not correct? The coefficient of determination, denoted by r^2 is interpreted as the proportion of observed y variation that cannot be explained by the simple linear regression model. The higher the value of the coefficient of determination, the more successful is the simple linear regression model in explaining y variation. If the coefficient of determination is small, an analyst will usually want to search for an alternative model (either a nonlinear model or a...
