What is Regression Analysis ?

Regression analysis is a statistical method used to establish a mathematical relationship between two or more variables. It helps in understanding how the value of a dependent variable changes when any of the independent variables change. Commonly used in predictive modeling, regression analysis is widely applied in fields like economics, finance, engineering, and social sciences.

Features

• Support for Multiple Data Formats: Easily process CSV and other common data formats. • Linear and Non-Linear Models: Build both simple and complex regression models, including linear, polynomial, and logistic regression. • Statistical Measures: Access key metrics such as R-squared, coefficients, and p-values to evaluate model performance. • Customizable: Adjust variables, add polynomial terms, and apply transformations to refine your analysis. • Data Visualization: Generate plots to visualize relationships and residuals for better interpretation.

How to use Regression Analysis ?

  1. Prepare Your Data: Import your dataset, ensuring the target variable is continuous for linear regression or binary for logistic regression.
  2. Select Variables: Choose the dependent variable (target) and one or more independent variables (predictors).
  3. Perform Analysis: Run the regression model and analyze the results, including coefficients and statistical significance.
  4. Evaluate the Model: Use metrics like R-squared to assess the model's goodness of fit and make necessary adjustments.
  5. Interpret Results: Understand the relationships between variables and apply insights to predictions or decision-making.

Frequently Asked Questions

What is the difference between linear and logistic regression?
Linear regression is used for predicting continuous outcomes, while logistic regression is used for predicting binary outcomes.

What is R-squared in regression analysis?
R-squared (coefficient of determination) measures the proportion of variance in the dependent variable explained by the model. A higher R-squared indicates a better fit.

How do I improve the accuracy of my regression model?
You can improve accuracy by adding relevant features, handling multicollinearity, removing outliers, and using techniques like regularization or cross-validation.
