Dear All I wonder if any one in the list can please help me with this bootstrapping problem. I have raw data in sequence of failures and success with treatment. There were 5 failures and 30 successes. The sequence of failures (F) and success (S) were as follows SSSSSSSSSSSSSSSSSSSFSSSSSFSSFSSFFSS For CUSUM calculations each success gets a score of +2/7 and each failure gets a score of -12/7 *Using bootstrapping techniques (reordering the sequence 1000 times) I want to calculate the 95% confidence limits for CUSUM* I am not able to get the software I downloaded on to Excel, to provide me the confidence limits for this data using CUSUM I will appreciate help from anyone familiar with this tool Sincerely Jacob Puliyel Head Pediatrics St Stephens Hospital Delhi 110054 -- ___________________________ Jacob M.
