I would like to set up a calibration method for an instrument utilizing samples taken from a roll of product. The test method is destructive. Each roll of product has 400 sheets which could be tested. I would like to test 80 of them and use the data to set upper and lower control limits for the use of the other 320 sheets as calibration checks. Once I have the 80 sdamples tested, I would like to use bootstrapping to determine the upper and lower control limits for the future calibration checks to be made with the other 320 sheets selected at random over a period of several months. The question is: Is there a bootstrapping method that can be used with the Control Chart Builder to set up the control limits? Thanks for your help!
