Hello,

The other post of yours on plotting the regression line in the scatter plot has been answered.

MATLAB has a feature called Regression Learner where you can train your data on different models and check for results. The model which gives the lowest RSME score is the best for the given data.

For more information on how to use the Regression Learner, refer to the following link
