Regression Analysis
In regression analysis, a regression equation is determined based on the line of best fit– a line that best fits the data points plotted in a graph. This line is also called the regression line. The algebraic equation for the regression line is called the regression equation. It is represented as:
Multiple Regression
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...
Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
Calibration Curves: Linear Least Squares
For data that follow a straight line, the standard method for fitting is the linear...

Machine learning accurately predicts vehicle CO2 emissions using Worldwide Harmonized Light Vehicles Test Procedure data. A Decision Tree model achieved high accuracy, enabling informed decisions to reduce greenhouse gas emissions in transportation.
Area of Science:
- Environmental Science
- Transportation Engineering
- Data Science
Background:
- Greenhouse gas (GHG) emissions from transportation contribute significantly to climate change.
- Vehicle emissions testing is crucial for regulatory compliance and environmental protection.
- The Worldwide Harmonized Light Vehicles Test Procedure (WLTP) is a global standard for measuring light-duty vehicle emissions.
Purpose of the Study:
- To develop accurate predictive models for CO2 emissions in light-duty vehicles.
- To leverage machine learning for enhanced vehicle emissions analysis.
- To support informed decision-making for reducing transportation-related GHG emissions.
Main Methods:
- Utilized vehicle emissions data collected by the UK's Vehicle Certification Agency (VCA).
- Trained and evaluated six regression machine learning models to predict CO2 emissions.
- Implemented a Decision Tree Regression model for its superior accuracy.
Main Results:
- The Decision Tree Regression model demonstrated the highest accuracy with a Mean Absolute Error (MAE) of 2.20 and a Mean Absolute Percentage Error (MAPE) of 1.69%.
- A web application was developed for real-time CO2 emission estimations.
- The model effectively predicts CO2 emissions based on WLTP data.
Conclusions:
- Machine learning and AI approaches are effective tools for promoting sustainability in the transportation sector.
- Accurate CO2 emission prediction facilitates targeted strategies for GHG reduction.
- The developed application empowers users to make informed choices for environmental benefit.
