The basic idea is that if a variable is strongly predictive, it will likely remain predictive no matter how the data is split. This most specifically refers to:

A. machine learning
B. randomization
C. regularization
D. cross-validation


Sagot :

Final answer:

Cross-validation assesses predictive model performance; regression line proximity indicates predictor's influence; multiple regression enhances predictions.


Explanation:

Cross-validation is the process of assessing how well a predictive model performs on new data by splitting the data into subsets, training the model on some subsets, and testing it on others. If a variable is strongly predictive, it will consistently show its predictive power across different subsets, indicating its reliability.

In the context of regression analysis, the strength of a predictor variable's influence on the response variable can be determined by how closely data points align with the regression line. When most data points lie near the line, there is a strong relationship, signifying the predictor's impact on the response.

However, it's important to note that strong prediction does not always imply causation. Using techniques like multiple regression where multiple predictor variables are considered can enhance predictions and provide insights into relationships among variables.
