Yes, it is possible for R-squared to be high with a poor model. This can happen when the model is overfitting the data, meaning it is too complex and is memorizing the noise in the data rather than capturing the underlying patterns.
While a high R-squared value is generally desirable, it is not always a good thing. A high R-squared value can indicate overfitting or model complexity, rather than a strong relationship between the variables.
Coefficient of Determination is always a good thing
R-squared is just one of several measures of goodness of fit, including the Mean Absolute Error (MAE) and the Mean Squared Error (MSE). While R-squared provides a measure of the proportion of variance explained, MAE and MSE provide a measure of the average distance between predicted and actual values.
However, there are also risks associated with Coefficient of Determination, including:
Coefficient of Determination is a powerful statistical tool that offers a range of opportunities for businesses, researchers, and policymakers. By understanding how it works, common questions, and realistic risks, you can make more informed decisions and drive business success.

R-squared is actually a measure of goodness of fit, not accuracy. While high R-squared values indicate a good fit, they do not necessarily imply accuracy.
How Coefficient of Determination Works
Coefficient of Determination, or R-squared, is a statistical measure that quantifies the proportion of the variance in the dependent variable that is predictable from the independent variable(s). It ranges from 0 to 1, with higher values indicating a stronger relationship between the variables. In simple terms, R-squared measures how well a model fits the data, with values close to 1 indicating a good fit and values close to 0 indicating a poor fit.
