Verify that the log-likelihood of model (7.7) is (sum_{i=1}^{k}left[n_{i} lambda-exp (lambda) ight]). (a) Compute MLE of (lambda).

Verify that the log-likelihood of model (7.7) is \(\sum_{i=1}^{k}\left[n_{i} \lambda-\exp (\lambda)\right]\).

(a) Compute MLE of \(\lambda\).

(b) Compute the Pearson chi-square statistic and compare it with (2.7).
