1. MSE Is the Complete Expected Squared Error under One Theta Law

Use scalar theta=-12, complete listed estimator values=[-13, -12, -11] and aligned probabilities=[1/4, 1/2, 1/4] under this same P_theta. Values and probabilities are exact rationals; probabilities are nonnegative and sum to1. Listed zero-mass rows remain in the data and contribute0. Output rows sort values numerically without separating them from their probabilities. Give (theta, weighted_error_rows, MSE, certificate).

View answer and explanation

Each output row is [estimator value,probability,squared error,weighted squared error]. Sum every weighted loss directly. Do not replace the definition with bias-variance decomposition, one realized loss or a variance computed under another law. The exact result, retaining the requested order, is (-12, [[-13, 1/4, 1, 1/4], [-12, 1/2, 0, 0], [-11, 1/4, 1, 1/4]], 1/2, direct_expected_squared_error_without_bias_variance_decomposition).
