Two Hypotheses of Independence for the Recognition of Qualitative Co-occurrences in Small Amounts of Data
George F. Estabrook · Historical Methods A Journal of Quantitative and Interdisciplinary History · 2002
The amount of data with which a historian works is sometimes limited by the availability of sources. When qualitative distinctions are to be compared in the context of only a small amount of data, ACTUS, a computer application originally described in this journal in 1989 by Carl B. Estabrook and George F. Estabrook, may enable a scholar to make a statistically supported interpretation in cases where he or she might otherwise have avoided interpretation, have made a purely verbal argument, or have even been misled. The present work presents ACTUS2, which implements several new hypotheses of independence.
