Question :A well-known example involving the Poisson model was described by LJ Bortkiewickz (1868-1931). The data refer to the annual number of deaths by horse kicks in battalions of army soldiers. Fourteen battalions were examined over number of years, resulting in a total of 200 battalions-years.

Number of deaths: (k) 0 1 2 3 4 ≥ 5

_________________________________________________

Number of battalions-years (nk): 109 65 22 3 1 0

Set a simple Poisson model and assess the quality of fit of the model. (To evaluate the quality of fit of the model you can use a chi-square test, comparing the observed values and the fitted values).

Can someone help me with this ?
