Dear all,
I need to run a simple linear regression such that:
y = b0 + b1*x1 + (1-b1)*x2 + e
which I know I can use:
lm(y ~ I(x1 - x2) + offset(x2)).
However, I also need to restrict the coefficient b1 to be between 0 and 1.
Is there any way to include such restriction in the linear regression
estimation?
I saw suggestion related with the function Solve.QP, but I really did not
understand such method.
Thanks in advance,
Julia
