Result
The book has the following results:
- Beta = 0.753, Lambda = 1.53
- [math]\displaystyle{ \,\!X^{2} }[/math] = 5.5, critical value = 7.8 (Assume significance level = 0.1. Since [math]\displaystyle{ \,\!X^{2} }[/math] < critical value can fail to reject hypothesis that the Crow-AMSAA model fits the data).
