Which of the following describes the 'Consistency' of an estimator θ^n\hat{\theta}_nθ^n?
The variance of the estimator approaches 0 as n→∞n \to \inftyn→∞.
The estimator converges in probability to the true parameter θ\thetaθ.
The estimator is unbiased for all nnn.
The estimator is the Minimum Variance Unbiased Estimator (MVUE).
