Does this even make sense?(adsbygoogle = window.adsbygoogle || []).push({});

Am told to do a multiple regression analysis. The response variable and the explanatory variables add up and should give up ~100 percent of the total product. Example:

Milk = water + fat + protein ~= 100% (all are in terms of percentages)

The regression I was asked to do is

protein = β + moisture*γ + fat*δ

So we can calculate protein without having to measure it (done on some test samples)

This to me makes absolutely no sense...I just can't put my finger on exactly why this is wrong (or if it even is)
