Expected value of a poisson process - Mathematics Stack Exchange
Feb 11, 2016 · Remember that Poisson processes have stationary and independent increments. The number of events in any time interval of length t t is Poisson distributed with mean λt λ t. E.g. E[N(t <a)] = λa E [N (t <a)] = λ a. In the same fashion you have. P[X(t + s) − X(s) = n] = P[Po(λt) = n] =e−λt(λt)n n! P [X (t + s) − X (s) = n] = P [P o ...

The number of breakdowns per week for a type of computer is a random variable Y having a Poisson distribution with mean μ. A random sample Y1; Y2, .... Yn of observations on the weekly number of breakdowns is available. The weekly cost of repairing the breakdowns is C = 3Y +Y2 C = 3 Y + Y 2. Show that E[C] = 4μ +μ2 E [C] = 4 μ + μ 2.
probability - Expected value of 2 Poisson distributions
Expected value of 2 Poisson distributions. Let X X and Y Y be independet Poisson random variables with parameters λ λ and μ μ. I have to calculate E((X + Y)2) E ((X + Y) 2) . What I did: E[(X + Y)2] = E[X2] + E[Y2] + 2EXEY E [(X + Y) 2] = E [X 2] + E [Y 2] + 2 E X E Y. I know that 2EXEY = 2λμ 2 E X E Y = 2 λ μ, but I don't know how to ...

probability - Why is Poisson distribution's expected value not on …
Nov 23, 2021 · $\begingroup$ The expected value is essentially the value that would occur "on average" -- if you were to repeatedly sample values from the distribution and take the running average, the running average would converge to the expected value of the distribution. For example, if you kept rolling a standard die repeatedly, you would find that the ...
expected value - Poisson times Binomial distributions
Dec 31, 2020 · Therefore, the unconditional distribution of X is Poisson with rate pλ. This would imply, for instance, Pr [X = 1] = pλe − pλ. However, as I have stated, NX is not the same thing: Pr [NX = 1] = Pr [(N = 1) ∩ (X = 1)] = λe − λp. So when you write " XN should follow a Poisson distribution with mean pλ," you are incorrect.
