Dear Don,
I done the plot and the lines, and it’s fine.
I’ll have 10 values on sample. It’s generating (on simulation), that’s why that huge outlier, and the other missing points.
The graph I’ve done, is just an example, just to illustrate what I have to get, but off course with 10 points in sample, and all the other specificityies.
Best,
RO
Atenciosamente,
Rosa Oliveira
