C DETAILED VAR MODEL RESULTS FOR BLOB GAS BASE FEE AND GAS BASE FEE
This section presents the detailed results from the VAR model analysis conducted on the blob gas base fee and the gas base fee. The analysis includes various statistical tests and model estimations to assess the dynamics and relation between these two key metrics within the network’s pricing mechanism.
C.1 ADF test results
Table 11 displays the results of the ADF test, used to check the stationarity of the time series data for both the gas base fee and the blob gas base fee. Result confirmed that the Base Fee and Blob Gas Base Fee time series are stationary. The test statistics of -6.3719 and -10.5237 respectively, along with very low p-values. This indicates that the data are suitable for further econometric modeling, as they do not depend on time.
C.2 VAR model estimation output
Detailed results for the VAR model estimation are provided below, showing the full regression output for both the gas base fee and blob gas base fee equations.
Detailed results for the VAR model estimation are provided below, showing the full regression output for both the gas base fee and blob gas base fee equations. Table 12 summarizes the overall model diagnostics including the number of equations, observations, log likelihood, and several information criteria that help in assessing the model fit. Table 16 presents the estimated coefficients and associated statistics for each variable within the equations, detailing the individual impacts in the model.
Table 12 summarizes key metrics from the VAR model regression results. The table captures essential information such as the number of equations modeled, total observations considered, and various statistical measures including the Akaike Information Criterion (AIC), Bayesian Information Criterion (BIC), Hannan-Quinn Information Criterion (HQIC), and Final Prediction Error (FPE). These metrics provide insights into the model’s performance and its predictive accuracy.
C.3 Correlation matrix of residuals
Table 13 presents the correlation matrix of residuals for the gas base fee and blob gas base fee. The near-zero correlation coefficients between the residuals of different equations suggest that the residuals are uncorrelated.
Table 16 provides detailed VAR model estimates for the gas base fee and blob gas base fee. For the gas base fee, all lagged values are significant predictors, with particularly strong influence from L1, evidenced by a high t-statistic of 155.252 and a p-value less than 0.001.
