The Gain index is simply the "estimate," (basically mean NCE change) divided by the standard error, which tells us the number of standard errors from the growth standard (0, ie staying at the same place on the bell curve) the mean NCE change is. Hence, any gain index of 2 or greater is "Most Effective" since the mean NCE change (Estimate) is 2 or more standard errors from the growth standard. It's all about the number of standard errors from 0 change the mean gain is.Bonny Buffingtonhttp://www.blogger.com/profile/10778602948803715504noreply@blogger.com
