I want to increase proportional increase weightage.
For example, I have weights
w1 = 0.4 w2 = 0.3 w3 = 0.2 w4 = 0.1
with a constraint that the total sum of the weights should always be 1 i.e
w1 + w2 + w3 + w4 = 1
Now, w4 has been removed. I want to proportionally increase w1, w2 and w3. so that
w1 -> 0.44 w2 -> 0.33 w3 -> 0.22
Also, the total sum of the weights should always be 1 i.e
w1 + w2 + w3 = 1.
How to do it mathematically?
