A frequency distribution function derived from a stochastic model considering human behaviors and its comparison with an empirical bibliometric distribution

  • N. Onodera


Simon's stochastic model is extended to take both ‘selective’ and ‘random’ factors in human behaviors into consideration. The resulting distribution function is of ‘non-steadystate’ type and approaches the Poisson distribution at the random limit while the Yule (or Zipf) distribution at the selective limit. A comparison of the theoretical distribution with an observed one for classification items indexed in a bibliorgraphic database is made. The results give some insights into statistical features of a class in which the total number of elements is fixed.
