摘要：

Based on one observation X from a N(theta, theta) distribution where theta(> 0) is an unknown parameter, this article provides an exact expression of the minimum variance unbiased estimator of 0 based on the complete and sufficient statistic vertical bar X vertical bar. Even though N(theta, theta) belongs to a one-parameter exponential family, I discuss some small surprises and intricacies that are worth noting.
