bug in 8.7 Glossary - bias (of an estimator): #24

Closed ToshiKurokawa closed 2 years ago

ToshiKurokawa commented 9 years ago

The current (2.0.27) definition of bias (of an estimator): The tendency of an estimator to be above or below the actual value of the parameter, when averaged over repeated experiments. should be read as The tendency of estimates by an estimator to be above or below the actual value of the parameter, when averaged over repeated experiments.

Yes, quite right. I will change it to:

The tendency an estimator to produce estimates above or below the actual value of the parameter, when averaged over repeated experiments.

Thanks! Allen
