Survivorship bias
| Глоссарий экономических терминов |
Usually pertaining to fund manager or individual investor performance. suppose we examined the performance over the last ten years of a group of managers that exist today. this performance is biased upwards because we are only considering those that survived for 10 years. that is, some dropped out because of poor performance. hence, in evaluating performance, one has to be careful to include both the current and the managers that dropped out of the sample due to poor performance.

Bias, английский
- Current or voltage applied to a circuit to set a reference operating level for proper circuit
- A measurement procedure or estimator is said to be biased if, on the average, it gives an answer that differs from the truth. the bias is the average (expected) difference between the measurement and the truth. for example, if you get on the scale with clothes on, that biases the measurement to be larger than your true weight (this would be a positive bias). the design of an experiment or of a survey can also lead to bias. bias can be deliberate, but it is not necessarily so. see also nonresponse bias.
- A systematic difference or systematic error between an observed value and some measure of the truth. generally used to describe the inaccuracy of a method relative to a comparative method in a method comparison experiment. it also has a specific meaning in the statistical t-test, where bias equals the difference between the mean values of the two methods being compared or the average of all the differences between the paired sample values.
