Lasso Regression

Description: Lasso regression is a regression analysis method that combines variable selection and regularization to improve the accuracy and interpretability of statistical models. Its name comes from ‘Least Absolute Shrinkage and Selection Operator’, reflecting its ability to reduce the size of variable coefficients through the penalty of the sum of the absolute values of the coefficients. This not only helps prevent overfitting but also allows for the automatic identification and selection of the most relevant variables in a dataset. Unlike traditional linear regression, which may include all variables regardless of their relevance, Lasso regression tends to completely eliminate some variables by assigning them a coefficient of zero. This approach is particularly useful in situations where there are many predictive variables, some of which may be irrelevant or redundant. Lasso regression is widely used across various disciplines, including statistics, data science, and machine learning, where model simplicity and interpretability are crucial. Additionally, it is a valuable tool in data preprocessing, as it helps clean and reduce the dimensionality of datasets before applying more complex models.
