Dear All, I would greatly appreciate if someone was so kind and share with me or us an R-package OR R-script example that calculate Eta correlation coefficient between a nominal (independent) and an interval (dependent) variable in R in a similar way as SPSS calculates it through crosstabulation tab. Thank you VERY MUCH. I am looking forward to receiving your reply at your earliest convenience. Christos Giannoulis [[alternative HTML version deleted]]
