| Tiivistelmä: | The paper rejects the stationarity of the beta distribution for 1926-85 for the entire period. However, results for pairs of five-year estimation periods are more consistent with stationarity. Excluding two aberrant periods, the number of rejections of stationarity is consistent with chance. For practical purposes the distribution of betas may be regarded as stationary. |
