Let y 1 , y 2 , . . . , y n be a random sample
Question:
Let y1, y2, . . . , yn be a random sample of size n from the pdf fY(y; θ) = 2y/θ2, 0 ≤ y ≤ θ. Find a formula for the method of moments estimate for θ. Compare the values of the method of moments estimate and the maximum likelihood estimate if a random sample of size 5 consists of the numbers 17, 92, 46, 39, and 56
