I'm working on a continuing problem. The current stage of the problem can
be summarized as follows:
Three columns of data, rational numbers, as X variables, X1, X2, X3. One Y
column, also rational numbers. Total number of observations is around
150,000. The range of Y is from 1 to 15.
I know that there exists multiple sets of combinations of X1, X2, X3 that,
when seen together, result in an 'expected' output of Y=8.000.
I'm after a mathematical rule, or at least a set of these combinations,
involving X1, X2, X3, that has expected Y output of 8.000.
Any help would be greatly appreciated.
Thanks,
Nicholas
