I am trying to solve the following...
W = pX
X is an i x 1 vector of known values (i is the number of observations in my sample)
p is a constant and is negative (it is unknown).
W is an i x1 vector of unknown values.
The sum of the values in W needs to equal zero. (w1 + w2 + w3 + ...+ wi = 0)
I am trying to solve for W.
I am not sure how to set up this problem so that I can solve for W.
Is this something that I can do using proc IML?
If so, can you please help show me how I can set it up.... I have been struggling with this all day and any help or advice is appreciated!
