What is one key advantage of separate sampling in model building?

Separate sampling in model building allows for the division of the dataset into distinct subsets, which can enhance the training and validation process of a model. One significant advantage is the reduction in required cases needed for model training and validation. By utilizing separate sampling, you can effectively create a representative sample for training while reserving another subset for validation or testing purposes. This approach ensures that the model is built on a broad, diverse set while also allowing for robust evaluation metrics without requiring the entire dataset for either phase.

This method helps ensure that the model does not overfit by providing clear boundaries between training and validation data, ultimately leading to a more efficient use of the available data. In scenarios where data is limited, this advantage becomes particularly crucial, as it maximizes the utility of the dataset while still striving for model reliability and accuracy.
