Well-behaved statistic

In statistics, a "well-behaved" statistic generally refers to a statistic that has desirable properties such as consistency, unbiasedness, efficiency, and robustness. These properties make the statistic reliable for inference and analysis. Here are some aspects that typically characterize a well-behaved statistic: 1. **Unbiasedness**: A statistic is considered unbiased if its expected value is equal to the parameter it is estimating, meaning that on average, it hits the true value.
