All three statistics (standard error of estimate, coefficient of determination, and t-test of the slope) are commonly used to determine whether a linear model should be employed. The standard error of estimate measures how accurately the model predicts the response variable, while the coefficient of determination (R-squared) measures the proportion of variability in the response variable that is explained by the linear model. The t-test of the slope tests whether the linear relationship between the predictor and response variables is statistically significant. Using all three statistics can provide a more comprehensive evaluation of the linear model.
