About This Template
Diagnose autocorrelation in your regression residuals with this Serial Correlation Test Calculator Excel template. Whether you are running time series regressions, panel data models, or econometric analysis, this template provides instant interpretation of both the Durbin-Watson and Breusch-Godfrey test statistics.
What You Can Calculate
This template includes two powerful serial correlation tests:
- Durbin-Watson Test - Detects first-order (AR(1)) autocorrelation using critical bounds from Savin-White tables. Get dL and dU bounds, implied autocorrelation coefficient (rho), and a clear five-zone decision.
- Breusch-Godfrey Test - Tests for higher-order AR(p) autocorrelation using the LM statistic. Works with lagged dependent variables where DW cannot.
Required Inputs
For the DW test, enter your DW statistic from regression output (Stata, R, Python, EViews, etc.), sample size (n=15-200), number of regressors (k=1-5), and significance level. For the BG test, enter sample size, R-squared from the auxiliary regression, number of AR lags, and significance level.
Methodology
The Durbin-Watson statistic is calculated as DW = sum(u_t - u_{t-1})^2 / sum(u_t^2), and approximately equals 2(1-rho). The template uses Savin-White critical value tables with linear interpolation for non-tabulated sample sizes. The Breusch-Godfrey LM statistic equals n times R-squared from the auxiliary regression, distributed as chi-squared with p degrees of freedom.
Assumptions & Limitations
- DW test requires strictly exogenous regressors (invalid with lagged dependent variables)
- DW bounds are tabulated for n=15-200 and k=1-5 only
- BG test assumes asymptotic chi-squared distribution
- For educational purposes only
Frequently Asked Questions
Yes, this Excel template includes separate input/output sections for both tests. The DW section uses a comprehensive lookup table with Savin-White critical bounds (covering n=15-200 and k=1-5), while the BG section computes the LM statistic, chi-squared critical value, and p-value using Excel built-in CHIDIST and CHIINV functions.
The template uses linear interpolation for n values between tabulated entries (e.g., n=42 interpolates between n=40 and n=45). The hidden DW_Bounds sheet contains the full Savin-White table, and the lookup formulas automatically interpolate when needed.
Yes. For the DW test, simply enter the Durbin-Watson statistic from your regression output (Stata, R, Python, EViews, etc.) along with your sample size and number of regressors. For the BG test, run the auxiliary regression in your software and enter the R-squared from that regression. The template handles all the critical value lookups and decision logic.
