Poisson Maximum Likelihood Estimation
...arry out some maximum likelihood estimation and I'm not
making much headway, and I'm hoping that someone will be able to point me in
the right direction.
I am modelling mortality statistics. One way to do this is to model the
mortality rate (or, more accurately, log of the mortality rate, log_m) as
(say) a constant plus a proportion of age, plus time, so:
r_1 <- lm(formula=log_m ~ age + time)
summary(r_1)
However, an alternative approach is to use try and estimate the number of
deaths from the poisson mean mortality rate, and the number of people, with
the poisson mean being defined...
