R and R Squared are statistical measures used to evaluate the relationship between a dependent variable and one or more independent variables. R represents the correlation coefficient, which measures the strength and direction of the linear relationship between two variables. R Squared, on the other hand, represents the coefficient of determination, which measures the proportion of the variance in the dependent variable that is predictable from the independent variable(s).
While R and R Squared are designed for linear relationships, there are alternative statistical measures, such as the coefficient of determination for non-linear relationships, that can be used in more complex scenarios.
