How can you interpret the coefficients in a linear regression output in Excel?

**Answer:** In a linear regression output in Excel, the coefficients represent the estimated impact of the independent variables on the dependent variable. The coefficient for each independent variable indicates the change in the dependent variable associated with a one-unit change in that independent variable, holding other variables constant. Positive coefficients indicate a positive relationship, while negative coefficients indicate a negative relationship. The magnitude of the coefficient represents the strength of the relationship.

How can you assess the goodness-of-fit in a linear regression analysis using Excel?

**Answer:** To assess the goodness-of-fit in a linear regression analysis using Excel, focus on the R-squared value. R-squared (or coefficient of determination) is a measure of how well the regression line fits the data. It ranges from 0 to 1, with 1 indicating a perfect fit. A higher R-squared value indicates a better fit and suggests that the independent variables explain a larger proportion of the variation in the dependent variable.

How can you use the FORECAST function in Excel for forecasting?

**Answer:** The FORECAST function in Excel is a useful tool for forecasting based on historical data. To use it, follow these steps:

- Ensure your data is organised with the time periods and corresponding values.
- Enter the forecast period (x-value) in a separate cell.
- Use the FORECAST function, specifying the forecast period, the known y-values, and the known x-values.
- Excel will calculate the forecasted value based on the linear regression equation derived from the known data.

How can you evaluate the accuracy of a forecast in Excel?

**Answer:** To evaluate the accuracy of a forecast in Excel, you can use various metrics such as Mean Absolute Error (MAE), Mean Squared Error (MSE), or Root Mean Squared Error (RMSE). These metrics compare the forecasted values to the actual values, providing a measure of the forecast’s accuracy. Lower values indicate a better fit and higher accuracy. You can calculate these metrics by subtracting the actual values from the forecasted values, squaring the differences, taking the average, and in the case of RMSE, taking the square root.
