for the intended purpose as a result of the following reasons:1
the data set included 10,193 projects, which is 3.5 times more
than the minimum required historic data outlined by Raviv1979
and2the data set contained 5,588 projects i.e., 54.82% of total
projects that did not witness any claims and disputes and thus,
eliminating the problem of adverse selection. This would provide
more confidence in the outcomes generated out of applying the
concept of RRG on the CALTRANS data set.
