ppois
A quick question!
The number of episodes per year of otitis media follows a Possion
distribution with lambda = 1.6 episodes per year. Wouldn't the
probability of getting 3 or more episodes of otitis media in the first
2 years of life be:
> ppois(q=3, lambda=1.6*2, lower.tail = TRUE, log.p = FALSE)
[1] 0.6025197
I am confused with the lambda and 3 or more..
thx much
