It is the cumulative distribution function of Poisson when the number of

The functional form given in the post written by Ssuhanchen captures my
eyes. It is the cumulative distribution function of Poisson when the
number of counts is less than or equal to 2 with unknown parameter
mu=x/2. Since it is a nonlinear function, there may be multiple
solutions but the
Got it! Thanks!
I find a useful function, uniroot.all, in package rootSolve.
I hope it will also be helpful to everybody.

no, it is not my homework.
I would like to know if there is relevant function to solve this equation in
R?
Could you please give me a hint or suggestion please.
Thanks!

Hi!
I want to use R to calculate the variable x which is in a complex equation
in below:

Σ[exp(-x/2)*(x^k)/(2^k*k!)]=0.05
k=0
how to solve this equation to get the exact x in R?
Is this homework? Sure looks like it. Talk to your prof. Or do a

For a _numerical_ solution, if f(x) is your function, use uniroot to find a
Hi,
The solution x to the equation is the parmater lambda = x/2 of a Poisson
distribution with probability of 0.05 for the number of occurrence 2 or
fewer.
