Regression

rɪˈɡrɛʃən

Regression is a statistical method used in data science and machine learning to model the relationship between a dependent variable and one or more independent variables. It aims to predict the value of the dependent variable based on the values of the independent variables. Common types of regression include linear regression, logistic regression, and polynomial regression, each with its own use case. Regression analysis is widely applied in various fields, including finance for predicting stock prices, in healthcare for estimating patient outcomes, and in marketing for forecasting sales. It is a fundamental technique for understanding trends and making informed decisions based on data.
