Here, the quantile of Poisson distribution for the last two values of X creates an infinity value.
I am not able to digest it. I will be glad if you can help out in getting these two values. It is supposed to be approx to them i.e. 119 and 139.
Thanks
x=c(2.54,5.08,7.62,7.62, 10.16,12.70,15.24,15.24 , 17.78,
20.32,22.86,25.40,27.94 ,27.94,30.48 ,30.48,33.02,35.56,38.10,
40.64,43.18 ,45.72, 48.26,58.42,68.58,88.90,93.98,119.38,139.70)
m=mean(x)
a=ppois(x,lambda = mean(x))
qpois(a, lambda = mean(x))
