Again, very helpful, thank you. How can you say if the change in measure of a person is significant or not? What are meanings of the three lines in the scatter plot? I see that person no1 has ~ +2.5 logits change but the position is nearby the dashed-line; person no27 has only ~+1 logit change but stay outside of the 2 solid lines. I am confused.
I learned so much!! Thank you!! But in 24 minute 15 second, 'Chart 2 (Sheet1)' is trend line not regression line. The regression line is in 'Measure(pf1.txt)-Measure (Sheet2)'. Am I right?
thanks, Pros. I am curious if stacking is possible to be used in FACETs? I searched the help document but it did not mention something related to the repeated measure.
