Regression analysis is a statistical method employed to predict continuous outcomes by examining relationships between variables. It covers both simple and multiple linear regression techniques using Python, emphasizing model fitting and evaluation metrics for effective predictive performance.
Regression is used to predict continuous values.
Simple regression involves one input, while multiple regression utilizes several independent variables.
Scikit-learn simplifies the processes of model fitting and evaluation.
Evaluation metrics such as MAE, MSE, and R-squared are essential for assessing model performance.
Visualizing regression and verifying model assumptions are critical for accurate predictions.
A statistical method used to examine the relationship between variables, particularly to predict a continuous outcome.
A regression method that models the relationship between a single independent variable and a dependent variable.
A regression approach that uses two or more independent variables to predict a dependent variable.
Statistical measures such as MAE, MSE, and R-squared that assess the performance of regression models.
Conditions such as linearity, homoscedasticity, and absence of multicollinearity that must be validated for reliable predictions.
