You can find the differences in the paired samples, then calculate the mean and standard deviation of the differences, then use this one-sample template: kzbin.info/www/bejne/r57YpImbYqtnipo

Suppose under minimax and optimistic we found 24,23,23 how do we choose our min regret . I know books said we add an additional factor but to were exactly ?

Will always the slack variables become non-basic for any simplex compatible problem once the cj - zj row <= 0? That would mean that we have the solution for all x's on the RHS and we wouldn't need to calculate the remaining x's from the f(x) value.

Can you explain why for Minimax regret, we do not take (15+18 =) 33 as the value instead. Why is 15 ignored, it could be relevant as to encapsulate two of the three types of economy. I understand in this example, mutual funds would still be optimal, but say if the mutual funds growing economy opportunity loss was 20, my question would be valid to possibly change the decision?
@joshemman
@joshemman Күн бұрын
Only one of the states (economies) could occur, so you have to choose the Max (18).

Please 1. Solve the following linear programming problem using the Simplex Method and discuss whether you find an optimal solution. Maximize Z = 30X1 + 50X2 Subject to the constraints: 3X1 + X2 ≥ 9 X1 + 2X2 ≥ 12 X1 + X2 ≥ 9 and X1, X2 ≥ 0
@joshemman

This is clearly an unbounded solution case. You cannot have a maximum if all your constraints are ≥.
