Question

When testing a model using the predict() function, do we input both X and y data?

1) True
2) False

Answer 1

When using the predict() function to test a model, we only need to input the X data, not the y data.

Step-by-step explanation:

When testing a model using the predict() function, we only need to input the X data, not the y data. The predict() function uses the trained model to make predictions on new data points.

For example, if we have a linear regression model that predicts house prices based on features like size, location, and number of rooms, we can use the predict() function to input new values for these features and get the predicted house price.

So, the correct answer to the question is 2) False. We only need to provide the independent variables (X data) when using the predict() function, not the dependent variable (y data).
