In Excel, the summary output worksheet for linear regression typically includes key statistics such as the coefficient estimates, standard errors, t-values, p-values, and measures of fit such as R-squared and adjusted R-squared.

The coefficient estimates represent the slopes of the regression line for each independent variable, while the standard errors indicate the precision of these estimates. The t-values are calculated by dividing the coefficient estimate by its standard error, and the associated p-values indicate the significance of each variable in predicting the dependent variable.

The R-squared value represents the proportion of variance in the dependent variable explained by the independent variables in the model. Adjusted R-squared adjusts for the number of predictors in the model, providing a more accurate measure of model fit when comparing models with different numbers of predictors.

Overall, interpreting the Excel summary output involves assessing the significance of individual predictors, the overall fit of the model, and the predictive power of the regression equation in explaining the variability in the dependent variable.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
