        Why R Squared is Gaining Attention in the US

        R Squared, also known as the coefficient of determination, is a statistical measure that quantifies the proportion of variance in the dependent variable that is predictable from the independent variable(s). In simpler terms, it measures how well a model fits the data. R Squared ranges from 0 to 1, with higher values indicating a better fit. A value of 1 means the model perfectly explains the data, while a value of 0 indicates that the model does not explain the data at all.
