Reading 8 (Miller), Chapter 3 AIM, small typo

Discussion in '2013 Errata' started by David Harper CFA FRM CIPM, Mar 6, 2013.

  1. "AIM: Calculate the mean and variance of sums of larger variables"

    should read:

    "AIM: Calculate the mean and variance of sums of variables"


    =========================================

    from my email exchange on 3/6:

    Hi Steve & Bill,

    I hope you are doing well. Re AIM under Chapter 3 (Miller) Basic Statistics, I think instead of:
    “Calculate the mean and variance of sums of larger variables.” [sic, page 8]

    The intent is perhaps:
    “Calculate the mean and variance of sums of a large number of variables.” (as in, a portfolio of securities), I think?

    Thanks!

    David,

    The AIM should read:
    “Calculate the mean and variance of sums of variables”

    Apparently, the word “larger” crept into the document inadvertently.

    Thanks for pointing this out. We hope it did not cause too much difficulty.

    Bill
