Greetings and thanks in advance for any help For interest, if I sample values from a perfectly Normal distribution and then 'discretise' the values by applying class boundaries... When I recalculate the standard deviation of the discrete values, the estimate of sd will have increased compared to the estimate of sd for the sample values. Is there a correction formula that will adjust the sd in line with a continuous variable? . . ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at: . http://jse.stat.ncsu.edu/ . =================================================================
