Hello all, I have seen instructions for conducting post-hoc pairwise comparisons in R after running an ANOVA, Kruskal-Wallis Test, or Yuen�s Test.
Is there a method to subset data automatically to run an effect size test across different pairs? For example, if I want to run Cohen�s d to examine the differences in data between different days of the week. My X variables would be the pairs below. (Note that no data was collected on Saturday.) I can subset the data manually and apply the effect size to each pair. Is there a way in R to create the pairs and run the effect size test all at once? Monday-Tuesday Monday-Wednesday Monday-Thursday Monday-Friday Monday-Sunday Tuesday-Wednesday Tuesday-Thursday Tuesday-Friday Tuesday-Sunday Wednesday-Thursday Wednesday-Friday Wednesday-Sunday Thursday-Friday Thursday-Sunday Friday-Sunday Any assistance you can provide would be much appreciated. Thank you, Giovanna GIOVANNA BADIA | Assessment Librarian, McGill University | Office of the Dean of Libraries | giovanna.ba...@mcgill.ca [[alternative HTML version deleted]]
