摘要：

The 'fit' between blockmodels and data networks is extended from a binary to a continuous concept. An index of goodness-of-fit for α-fit blockmodels is proposed, based on the purity (density of 1's or 0's) of the submatrices of the data matrix(es) after the blockmodel partition is imposed. The characteristics of this index are compared with those of correlation coefficient. Some applications are described. © 1979.
