Is Your Linear Regression Analysis of Electric Car Energy Consumption Accurate?

[bradyj7]

Hi there,

I have performed a linear regression of the energy consumption of an electric car on 7 measured parameters. They are

1. Max acceleration
2. Average Acceleration
3. Average Velocity
4. Distance travelled
5. Standard Deviation Acceleration
6. Standard Deviation Velocity
7. Max power required

There originally was 25 parameters but, I narrowed it down to these 7 by investigating the relationships between the variables and using stepwise and best subsets regression. This is the simplest equation that I could get. I think that it is okay but I was just wondering if somebody could have a quick look at the output and see if anything major is wrong with it.

Here is the output

Thank you

Hello John,

Thank you for sharing your linear regression analysis. It looks like you have done a thorough job in narrowing down the parameters and using regression techniques to determine the best subset of variables. Your output does not show any major red flags, but there are a few things that you may want to consider.

Firstly, it would be helpful to provide some context for your analysis. What is the purpose of this regression? What is the dependent variable (energy consumption) and what are the independent variables (the 7 parameters)? This information will help to better understand the results and their implications.

Additionally, it would be useful to see the correlation coefficients for each of the independent variables with the dependent variable. This would provide insight into the strength and direction of the relationships between the variables.

Lastly, it may be beneficial to assess the assumptions of linear regression, such as normality and linearity, to ensure that they are met. This can help to validate the results and ensure the accuracy of the model.

Overall, it seems that you have put a lot of effort into your analysis and have a solid understanding of regression techniques. Keep up the good work and don't hesitate to seek out further guidance or feedback. Best of luck with your research!
