2Â Â Â Using the data in KIELMC.RAW, the following equations were estimated using the years 1978 and 1981:
ïž²log(price) 5 11.49 2 .547 nearinc 1 .394 y81?nearinc
(.26) Â (.058)Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â (.080)
n 5 321, R2 5 .220

ïž²log(price) 5 11.18 1 .563 y81 2 .403 y81?nearinc
(.27) Â (.044)Â Â Â Â Â Â Â Â Â (.067)
n 5 321, R2 5 .337.

Compare the estimates on the interaction term y81?nearinc with those from equation (13.9). Why are the estimates so different?
