The estimators of unknown population parameters are computed by taking the sample from the population and hence the estimated values vary with different samples drawn. If the bias of an estimator is zero, this means that the estimator is unbiased....

A statistic can bemore than one type. For example, the samplestandard deviationcan be used as a descriptive statistic to describe thestandard deviationof a sample. It can be used as an estimator: To estimate the population standard deviation. And it can be used to test a theory (ahypothesis...
This note is about attempting to remove the bias brought in by using sample standard deviation estimates to estimate an unknown true standard deviation of a population. We establish there is a bias, concentrate on why it is not important to remove it for reasonable sized samples, and (despite...
Similar to Hasbrouck and Seppi (2001), we construct a composite estimator, the first principal component of the low-frequency proxies, and find that it does not generally improve on the performance of the best individual proxies. The measures that best describe the level of the benchmark measur...

Most of the prior research has three significant flaws: first, it uses cross-sectional data, which doesn't adequately account for country-specific effects; second, it uses a multivariate test of causation, which could result in omission-of-variable bias; and third, it relies on those two issu...
Our study yields several noteworthy findings. Our regression analysis indicates that an aggregate measure of CSP lacks relevance to shareholder value. This illusory result arises due to aggregation bias, which masks the heterogeneous effects of different corporate social activities targeting diverse stakehold...
