Using Minitab 14, the relationship between NSC Production versus the four external factors (ASEAN) was tested, for the model (eq. 5), page 38:
The regression equation is
NSC Production = – 844172 + 71.8 ASEAN Crude – 585 ASEAN ACC
– 18.8 ASEAN SF&F Imports + 11740 Asia IP
S = 79019.6 R-Sq = 95.3% R-Sq(adj) = 76.5%
Table 23: Analysis of Variance: External Factors (ASEAN)
Analysis: The p-value (regression) is greater than a pre-selected a-level of 0.05, thus at least one coefficient is zero. The F-value, 5.22%, is less than the confidence level of 95%, thus the current model fits the data well.
Table 24: Multiple Regression Analysis: External Factors (ASEAN)
Analysis: The T-value for ASEAN Crude and Asia Index Prices are greater than a=0.05, thus with 95% confidence, the prediction is significant for these factors. Comparing the coefficient p-values to a=0.05, all predictors are statistically insignificant.
