[Solution] Let X_1,...,X_n be i.i.d. observations from an exponential (λ) distribution, the p.d.f. of X is given by Use the moment-generating function
Question: Let \({{X}_{1}},...,{{X}_{n}}\) be i.i.d. observations from an exponential ( \(\lambda \) ) distribution, the p.d.f. of X is given by
- Use the moment-generating function of X to find the distribution of (10 points)
- Show that T is sufficient for \(\lambda \). (8 points)
- It is easy to show that T is also complete for \(\lambda \). Find the UMVUE of (6 points)
