What happens when you overfit a regression model?

 

Question 25 options:

 

The model captures too much of the random variation in the sample data and fails to predict accurately for the population.

 

The p-value for the F-test of overall significance is greater than 0.05.

 

So many variables are added to the model that the Adjusted {"version":"1.1","math":"<math xmlns="http://www.w3.org/1998/Math/MathML"><msup><mi>R</mi><mn>2</mn></msup></math>"} value exceeds 1

 

None of the relationships in the model are found to be statistically significant.
