Show Suggested Answer

Suggested Answer: D

A predictive model is a mathematical function that estimates the probability of an outcome based on input data.When building a predictive model, the use of testing and validation samplesincreases the accuracy of models123. Testing and validation samples are subsets of data that are used to evaluate how well a model performs on new data that was not used to train the model. Testing and validation samples help prevent overfitting, which is when a model learns too much from the training data and fails to generalize to new data.
