Comparisons of Lasker's coefficient of relationship in a Venezuelan town in two different periods.
A formula for the standard error of Lasker's coefficient of relationship Ri derived from isonymy is proposed, and used to test for differences in relationship in two groups of pairs of spouses from the town of Quibor in Venezuela sampled one century apart. From analysis of the relationship, it was possible to attribute population growth also to immigration. Further, the study of the values of Ri showed that the surnames belonging to the male line are more frequent and stable in this population, which is characterized by a predominantly agricultural activity. From the analysis of the coefficients of relationship, the population of Quibor is also classified as patrilocal.
