Question 590: One Fixed Parameter-Independent Tie Order Produces a Total Finite Estimator

Original question and givens

Use complete theta labels=[a14, b14], observations=[x14, y14] and aligned exact probability rows=[[[3, 4], [1, 4]], [[1, 4], [3, 4]]]. Each theta row is nonnegative and sums to1. Sort labels with their associated rows/columns, never independently. Tie order=[a14, b14] is one complete parameter permutation, fixed independently of the unknown theta. Give (tie_order, estimator_rows, total_estimator, certificate).

Definition and scope

Keep each observation's complete argmax, then pick the first member in one fixed parameter-independent tie order, giving a total estimator.

Step-by-step derivation

Θ=[a14, b14]; Ω=[x14, y14]

[[3/4, 1/4], [1/4, 3/4]]

P_a14(Ω) := sum(3/4, 1/4)

P_a14(Ω) = 1

P_b14(Ω) := sum(1/4, 3/4)

P_b14(Ω) = 1

tie priority=[a14, b14]

one fixed ordering, independent of the observed outcome

parameter=a14; observed=x14

L(a14;x14)=3/4

parameter=b14; observed=x14

L(b14;x14)=1/4

[[a14, 3/4], [b14, 1/4]]

maximum=3/4; all argmax=[a14]

argmax(x14)=[a14]; priority=[a14, b14]

estimator(x14)=a14

parameter=a14; observed=y14

L(a14;y14)=1/4

parameter=b14; observed=y14

L(b14;y14)=3/4

[[a14, 1/4], [b14, 3/4]]

maximum=3/4; all argmax=[b14]

argmax(y14)=[b14]; priority=[a14, b14]

estimator(y14)=b14

defined on 2 outcomes

total on all 2 listed outcomes
