Hi all,
   I'm trying to do a test-retest reliability analysis on attachment loss measurement. Attachment loss is measured in millimeters ranging from 0 to about 14. my question is how to do this within ± 1 mm accuracy. Also for validity assessment (using gold standard), how could we measure the same variable within 1 mm accuracy.
  thanks,
  razina
