Clifford Nowell, Linda R. Stanley,

Evacuation and Crowd Dynamics

The authors address length-biased sampling that occurs when sampling is done at central locations in a shopping center. Correction techniques are presented for two situations: when the total length of stay is known or estimated and when only the recurrence time is known accurately. The techniques are illustrated with mall intercept data.
