On the Potential of Sample Size Invariant Measures for the Comparative Analysis of Author Productivity of Di erent Domains

In this paper we examine the usefulness of two sample size invariant measures for the comparative analysis of author productivity Most of the studies which have been carried out on modeling the quantitative structure of author productivity are mainly concerned with describing the given samples and little e ort has been devoted to clarifying the statistical status of the sample However author productivity data has a peculiar feature i e most of the statistical measures change systematically according to changes in the sample size which causes di culty in comparing di erent data of di erent sizes One way to compare author productivity in di erent domains whose sample data most probably varies in size is analyzing the developmental pro les of measures for growing sample size In this paper the potential of this approach is examined
