我试图反向预测从预测结果%的初始要求值,并且不能找到正确的公式来这样做(假设从输入值的下降,导致相同)。
下面是数据的例子:
A B C D E F G
Input Result % New Input New Result New % Required %
2000 700 35 1857.05 557.05 30 30
A = Raw data
B = Raw data
C = B / A
D = (A - B) * 1.4285 'This is the formula i need help with, i want this formula to calculate the required new input to receive result G but can only get result G currently by manually tweaking the number in D formula or causing a circular reference
E = D - (A - B)
F = E / D
G = User input
我希望用户在G中所需%键入,看到了新的输入电平变化对导致F.即%所需的数
希望这是有道理的,在此先感谢。
它是一个一次性的事情吗?在这种情况下,使用Goal Seek
