Hello /sci/, please help a brainlet out, I need this so bad. I'm trying to program an API that pulls financial data and need to know how to properly evaluate that data but am having major trouble.

Ok, here's how I am understanding my problem;

You have two tree's, an apple tree and an orange tree. The Apple tree has produced 60% of max fruit, the Orange tree has produced 40% of max fruit. Sunlight today makes the Orange tree produce 25% LESS fruit at some indeterminate time in the future, and sunlight today makes the Apple tree produce 25% MORE fruit at some indeterminate point in the future (IDPF) , but sunlight today decreases humidity by 10% at IDPF. Humidity today makes the orange tree produce 30% MORE fruit at some IDPF, where as humidity today makes the apple tree produce 75% MORE fruit at some IDPF, and humidity today causes 20% more sunlight at IDPF.

So, that's the problem as much as I can rationalize it. Now I'm not sure how to set this up into an equation to accurately evaluate this statement is the problem. For example, to highlight the variables let's say the Orange tree is producing 20% fruit now, Apple tree 50%, sunlight is at 40%, and humidity is at 70%. Is there a way to find what sunlight and humidity would have been at during an indeterminate period in the past to the tree's current yield? What is the expected yield of the trees at the indeterminate time in the future? How do I properly equate all of these variables, if I know everything except the humidity can I properly evaluate the equation to find humidity? What will the ratio of apples to oranges be in that scenario?

The actual problem is that I'm trying to equate three pieces of data to each other; the performance of GDP, which effects investment and The cycle. The business cycle itself, which effects GDP and investments. And Investments, which is just affected by GDP and Cycle but effects nothing.
