\nThe R-squared value always increases or remains the same with the addition of variables. It can never happen that an additional variable, no matter how insignificant, will decrease the value of R-squared. The key idea behind adjusted R-squared is that it penalises models for having a higher number of variables. Thus, if the value increases on the addition of a variable, we may conclude that that variable is significant, and vice-versa.\n<\/div>\n","tip":"","notChosenFeedback":""},"text":"

R-Squared Values Suppose you built a model with some features. Now you add another variable to the model.
