How will the R-squared value compare for the multiple linear regression versus the simple linear regression? Why? R-Squared: R-Squared is a measure used in regression to test the performance of any regression model. It represents the amount of variance in...

among the variables which one is more important than the other. The value will be higher than the R Square if a new independent variable improves the model or vice versa. In this dataset, the value of theAdjusted R Squareis 0.92. That means 92% of the points fit the regression line. ...
