Introduction to Statistical Decision Theory – Edition 2: Foundations of Estimation and Hypothesis Testing

1. Point Estimation Example Estimating Variance in the Normal Model Let \(X_1, \ldots, X_n \sim N(\mu, \sigma^2)\). We are interested in estimating \(\theta = \sigma^2\). Well-known estimators: Sample variance (unbiased): $$\hat{\sigma}^2 = \frac{1}{n-1} \sum_{i=1}^n (X_i…
