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?
