Forecast Pooling Weight

Problem

Combine two forecasts with a fixed weight: w1 * f1 + (1 - w1) * f2.

Return the pooled forecast. The weight w1 is between 0 and 1.

Hint

Simple averaging corresponds to w1 = 0.5.

case 1

in: [10,20,0.5]

expected: 15

case 2

in: [10,20,1]

expected: 10

case 3

in: [10,20,0]

expected: 20

case 4

in: [3,5,0.25]

expected: 4.5
