Dear R Users,
I would like to make a lesast squares regression similar to that what is
done by the command "lm". But additionally, I would like to impose some
restrictions:
1) The sum of all regression coefficients should be equal to 1.
2) Each coefficient should assume a value between 0 and 1. (inequality
restrictions)
Which command is the best to use in order to solve this problem in a
computationally efficient way?
Thank you in advance for your help,
Harald Bartel
