I sympathize with researchers who refuse to calculate CIs, because 99% of the time it will be interpreted the same way you do. CI does not imply that the population parameter is between Y and Z with X probability. To make statements like this you would need to consider a prior parameter distribution and combine it with the likelihood of the data. -- # syrahz_derzai ; at yahoo.com . . ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at: . http://jse.stat.ncsu.edu/ . =================================================================
