replace “0.0003” by “0.0002”

equations for Vi1 and Vi2 summation
should run from j=1 to 8, not from i=1 to 8
Page 158: First line
after first equation: replace “1000” by “5,000”
Page 188: In Table 9.1, Feature weight and
contribution for Finished basement (sq.ft.) should be 20.42 and 15,437; Total on last line
should be 51,532. Two lines below table “$237,678” should be “$232,349”. Four
lines below table “$56,861” should be “$51,532”
Page 210: 2-3 lines before Section 10.6: Replace “0.33” by “0.32” and “9.7%” by about “9%”.
