I have a problem. I have 8459 data points. These data points result in a savings of about 745.45 euros. Per year I have approx. 145148987 data points.
How do I now calculate an extrapolation for the whole year for these 8459 data points?
I could calculate something like this:
$$ \frac{745.45}{8459} = ~0.08812507 $$ $$ 0.08812507 * 145148987 = 12791265.20 $$
I would save about 12791265.20 for all data points - according to my calculation.
However, as far as I know it should be a free extrapolation - therefore the result would be wrong. Now how do I correctly calculate the savings for all data points?
