How To Correctly Interpret Your Eviews Outputs And Assignment Help Tips

EViews is one of the best statistical packages to analyze economic data and perform econometrics, times series forecasting, and data analysis. For the students studying statistics and econometrics, it is highly important to be able to analyze and interpret outputs given by EViews to complete assignments and use them in practice. This guide is intended to serve as a helpful reference on how to read through EViews outputs with examples of their interpretations in the recent years, coding samples, case studies, and/or further readings on the related topics.

However, anyone who is about to deal directly with the EViews outputs should have a basic understanding of econometric and statistical concepts. EViews mainly dealing with conducting regression analysis is very helpful in understanding the relationship amongst different variables in the data. The Eviews outputs normally displays coefficients, standard errors, t-statistics, p-values, R-squared, and others.

Components of EViews Outputs

1. Coefficients: Represent the estimated impact of independent variables on the dependent variable.
2. Standard Errors: Indicate the accuracy of the coefficient estimates.
3. T-Statistics: Show whether the coefficients are statistically significant.
4. P-Values: Help determine the significance level of the results.
5. R-Squared: Indicates the goodness-of-fit of the model.
6. Adjusted R-Squared: Adjusted for the number of predictors in the model.
7. F-Statistic: Tests the overall significance of the model.

Step-by-Step Interpretation

Example: Simple Linear Regression

Suppose you are analyzing the relationship between study hours and exam scores. You run a simple linear regression in EViews with exam scores as the dependent variable and study hours as the independent variable.

equation eq1.ls exam_score c study_hours

Here is a typical output you might get:

Interpreting the Output:

• Constant (C): The coefficient 50.123 suggests that if no hours are spent studying, the expected exam score is 50.123.
• Study Hours Coefficient: For every additional hour spent studying, the exam score increases by approximately 2.456 points. This can be interpreted as a positive correlation between the amount of time spent learning and the amount of credit achieved, meaning that more time spent preparing for a test result in a higher score. Being an objective value, it gives the actual measure of how much study time contributes toward enhanced performance.
• Standard Errors: Indicate the variability in the coefficient estimates. Smaller values suggest more precise estimates. Standard errors are used in the estimation of the accuracy of the coefficients derived from the analysis involving regression. Thus, smaller standard errors mean that the estimates are more accurate.
• T-Statistic and P-Value: Both coefficients have low p-values (0.0000 and 0.0001), indicating they are statistically significant at the 1% level. The t-statistic and p-value assist in identifying the importance of each estimated coefficient.
• R-Squared and Adjusted R-Squared: Not shown in the table but available in the EViews output. These values enable the determination of amount of variance in the dependent variable accounted for by the model. While the overall analysis looks at how well the entire model can predict the dependent variable, R-squared focuses more directly on the independent variable in question, in this case, study hours, to see if they are good at predicting the variation in the results of the exams. The adjusted R Squared also takes into account the number of independent variables that have been included, and therefore ensures more accurate evaluation of the fitness of the model in multiple regression.

Tips for Accurate Interpretation:

1. Check Assumptions: Ensure the regression assumptions (linearity, independence, homoscedasticity, normality) are met. These assumptions are critical for the validity of the regression results. Linearity assumes a straight-line relationship between variables. Independence means that the residuals are independent of each other. Homoscedasticity implies constant variance of errors, and normality indicates that the errors are normally distributed.
2. Residual Analysis: Examine residuals for any patterns that might suggest model issues. Analyzing residuals (the differences between observed and predicted values) helps identify any inconsistencies in the model. Patterns in residuals can indicate problems such as non-linearity, heteroscedasticity (unequal error variances), or autocorrelation, suggesting that the model may need adjustments.
3. Multicollinearity: Use Variance Inflation Factor (VIF) to check for multicollinearity among predictors. Multicollinearity occurs when predictor variables are highly correlated, which can distort the estimates of the coefficients making them difficult to interpret. The VIF quantifies how much the variance of a coefficient is inflated due to multicollinearity. High VIF (typically above 5 or 10, depending on the context) values indicate significant multicollinearity, necessitating corrective actions like removing or combining variables.
4. Model Fit: Consider adjusted R-squared for model fit, especially in multiple regression. Adjusted R-squared provides a more accurate measure of model performance by adjusting for the number of predictors. It prevents overestimating the model’s explanatory power, offering a realistic assessment of how well the model fits the data, particularly when multiple independent variables are involved.
5. Diagnostic Tests: Conduct tests like Durbin-Watson for autocorrelation. Diagnostic tests help identify potential problems in the regression model. The Durbin-Watson test specifically checks for autocorrelation, which occurs when residuals are correlated across observations. Detecting and correcting autocorrelation is essential to ensure the validity of the regression results and to improve the model’s predictive accuracy.
