| Tiivistelmä: | Schafer has analysed Belson's data obtained in 1962 using regression analysis. He found high non-linear correlations between the conventional and intensive approaches to readership surveys. A major result is that the superficial treatment of a large number of publications progressively handicaps smaller publications. |
