Question:

Suppose that W1,W2, and W3 are independent random variables, each of which has a normal with the following means and variances:
E(W1) = θ1 + θ2, Var(W1) = σ2,
E(W2) = θ1 + θ2 − 5, Var(W2) = σ2,
E(W3) = 2θ1 − 2θ2, Var(W3) = 4σ2.
Determine the M.L.E.’s of θ1, θ2, and σ2, and determine also the joint of these estimators. Distribution
The word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
