Subject:      Interpreting conjoint results
Content-Type: text/plain

Hi,

I'm analysing results of a conjoint study and have some difficulties interpreting the results.

Can anyone explain how the Pearson R and Kendall tau are calculated in the results?

Also, my results show high and significant values for R and tau but low and non significant tau for the holdouts. Does it mean that the linear model is good for explaining the results I have but it does not predict well? I'm not sure how to explain this and why this might happen.

Thanks
