Regression modeling is a crucial aspect of statistics and machine learning, helping us understand relationships between variables and make informed predictions. However, not all variables contribute equally to a model’s performance. Including too many predictors can lead to unnecessary complexity, making the model harder to interpret and less efficient. This is where stepwise regression comes … Read more
Understanding relationships between variables is fundamental in data science and machine learning. While linear regression is widely used, it often fails to capture complex patterns in data. Polynomial regression extends linear regression by fitting a nonlinear curve, making it suitable for datasets where relationships are not strictly linear. In this article, we will explore polynomial … Read more
