Linear Regression Skill
Linear Regression is a fundamental statistical and machine learning technique used for modeling the relationship between a dependent variable and one or more independent variables. The core idea is to find the best-fit linear equation that represents the linear relationship between the variables.
In a simple linear regression, there is one independent variable, while multiple independent variables are considered in multiple linear regression. The model aims to minimize the sum of squared differences between the observed and predicted values, and it expresses the relationship through coefficients and an intercept.

Linear regression finds extensive use in various fields, such as economics, finance, biology, and engineering, for tasks like predicting stock prices, estimating sales trends, or analyzing the impact of variables on an outcome. It provides a straightforward and interpretable model, making it a foundational tool in the statistical and machine learning toolbox.
