Best Practices for Curve Fitting
- Data Preprocessing: Ensure data cleanliness by handling missing values, outliers, and transforming variables if necessary to meet regression assumptions.
- Model Selection: Choose the appropriate regression model based on the nature of the relationship between variables and the assumptions of the model.
- Feature Engineering: Select relevant features and consider transforming variables or creating interaction terms to capture complex relationships.
- Model Evaluation: Assess model performance using metrics such as coefficient of determination (R2), mean squared error (MSE), and residual analysis to gauge goodness of fit and identify potential issues.
- Cross-Validation: Validate model performance using techniques like k-fold cross-validation to ensure robustness and generalizability.
Curve Fitting using Linear and Nonlinear Regression
Curve fitting, a fundamental technique in data analysis and machine learning, plays a pivotal role in modelling relationships between variables, predicting future outcomes, and uncovering underlying patterns in data.
