Inhoud:
An integrated description is given of some recently developed statistical methods for analysis of one or more samples of measurements of palaeocurrent data, including testing of isotropy, estimating mean or median directions together with assessments of the reliability of the estimates, comparing and combining information from two or more samples of data, and treating data measured as axes or undirected lines, rather than as vectors. Each method described is illustrated on a data set. The importance of these methods is that routine reporting of certain summary statistics for each sample will permit the information in the data to be compared with, and amalgamated with, data from other sources which have been summarized in similar fashion: access to all the individual palaeocurrent measurements is no longer necessary. Such compact methods of data reporting and integration of information have, hitherto, not been available in the geoscience literature.
