This can happen when the model is too simple or when there is not enough data. To address underfitting, you can add more variables, introduce polynomial degree variables, or use a more complex model.<\/p>\n<p>Adding more variables can help to capture the true relationship between the variables. However, it is important to only add variables that are truly related to the response variable. Otherwise, you may end up overfitting the data.<\/p>\n<p>Introducing polynomial degree variables can also help to capture the true relationship between the variables. This is because polynomials can be used to represent a wide range of relationships. However, it is important to choose the correct degree of polynomial.
