Edition 4ISBN: 978-0324660609 Exercise 1
In Example we added the quadratic terms pcnv2, ptime862, and inc862 to a linear model for narr86.
i) Use the data in CRIME1.RAW to add these same terms to the Poisson regression in Example
(ii) Compute the estimate of a2 given by
Is there evidence of overdispersion How should the Poisson MLE standard errors be adjusted
(iii) Use the results from parts (i) and (ii) and Table to compute the quasi-likelihood ratio statistic for joint significance of the three quadratic terms. What do you conclude
Determinants of Number of Arrests for Young Men
