On the use of hansen frequencies for estimating rates of behavior

  • Stephen E. Fienberg


When the occurrence of a behavior is governed by aPoisson process over time, then the mean rate of behavior can be estimated usingHansen frequencies, which record whether the behavior has occurred at least once or not at all in each of several time periods. Here this estimate of the mean rate of behavior, based onHansen frequencies, is compared with the usual estimate, and its properties as an estimate of the mean rate of behavior are discussed in cases where the behavior is not governed by aPoisson process.
