1. The dataset prussian in the pscl package lists the number of deaths by horsekick in the Prussian army by corp and year. Fit 2 models, model1=glm (y corp, family-poisson, data=prussian) model2=glm(y corp+year, family=poisson, data-prussian) b. Now assume that death rates are poisson but depend on neither corp or year. If this were a sample of 280 independent and identicially distributed random poisson variables, what would be the maximum likelihood estimate of the poisson rate X? c. Using modell, what is the estimated probability of 3 deaths by horsekick in a year in corp IIT
