Expanded coverage of evaluating software and hardware, and when to use COTS (commercial off-the-shelf software), is included. This chapter teaches a number of strategies for forecasting costs and advantages, which are essential to the dialogue of buying software and hardware. Below we present an excerpt of the output from this evaluation, exhibiting the 3 comparisons. Note that the Contrast Estimate for the first contrast is the imply of write for stage 1 minus the imply of write for level four , and certainly if we examine this estimate with the means of write by race we find forty six. Likewise, the second Contrast Estimate is the imply of write for level 2 minus the imply of writefor degree four , and the third Contrast Estimate is the mean of write for level three minus the imply of writefor level 4 . Note that the 3 Contrast Estimates correspond to the 3 coefficients from the regression analysis above.
