For instance, a high R-squared value does not necessarily mean that the model is reliable or accurate.
R-squared, also known as the coefficient of determination, measures the proportion of variance in the dependent variable that is explained by the independent variable(s). In simple terms, it indicates the strength of the relationship between the variables. An R-squared value close to 1 suggests a strong linear relationship, while a value close to 0 indicates no relationship. For example, if an analysis shows an R-squared value of 0.8, it means that 80% of the variation in the dependent variable can be explained by the independent variable.
