DEFF '08 enables senior executives to share knowledge, strategy and experience, in order to discuss the commercial issues surrounding the timely roll-out and sustainable business of the US DEF infrastructure for heavy duty diesel fleets.
Combining this information with the DEFF, it can be shown that under standard assumptions, the minimum sample size for nonresponse weights to improve the MSE of single-population estimates for the median of the 20 rating and report items is between 330 and 400.
The maximum inflation to MSE-based standard errors at sample sizes below the break-even thresholds discussed above is determined by the DEFF, and never exceeds 9 percent.
DEFFs for these nonresponse weights were calculated in order to assess the variance inflation from the use of nonresponse weights.
