Hi,
I can not solve my problem about logit transformation. The responses are % crystallinity so I should do logit transformation to the response data. But I can not do this transformation. Because minitab did not accept negative values. Is there any way to do this with minitab?
And the other question is how can I find the "confidence interval" in this situation?
Thank you for your time in advance.
