Hi,
I am trying to create a set of dummy variables to use within a multiple linear
regression and am unable to find the codes within the manuals.
For example i have:
Price Weight Clarity
IF VVS1 VVS2
500 8 1 0 0
1000 5.2 0 0 1
864 3 0 1 0
340 2.6 0 0 1
90 0.5 1 0 0
450 2.3 0 1 0
Where price is dependent upon weight (single value in each observation) and
clarity (split into three levels, IF, VVS1, VVS2).
I am having trouble telling the program that clarity is a set of 3 dummy
variables and keep getting error messages, what is the correct way?
Any helps is greatly appreciated.
Matthew
