Suppose that xı,... , In are a random sample of lifetimes for individuals diagnosed with a certain disease. Assume a model with where k is fixed and known Interest is in the parameter -P(X> 25; A) which gives the probability that an individual will survive more than 25 years with the disease. It can be shown that the cumulative distribution Determine the MLE of

Suppose that x1, . . . , xn are a random sample of lifetimes for individuals diagnosed with a certain disease. Assume a model with f(x; λ) = k(x/λ)^k−1 * e^−(x/λ)^k /λ, x > 0, where k is fixed and known. Interest is in the parameter ζ = P(X > 25; λ) which gives the probability that an individual will survive more than 25 years with the disease. It can be shown that the cumulative distribution is F(x; λ) =...
