Exercise 3: Statistical cross-dating

| No Comments

Overview In this exercise, you learn how to use an industry-standard software application to confirm visual cross-dating through statistical measures of similarity or dissimilarity. We'll use the program COFECHA to assess the quality of cross-dating in one set of tree-ring width measurements and to identify potential dating errors in another set.
