TeX.SE meta proposed to predict when their number one user, egreg, will reach 654321 reputation points.
I made a prediction based on a linear interpolation of the 90 past days rep.
I thought it would be an interesting question to illustrate MMA statistical possibilities, especially if some statistics gurus could demonstrate the use of high-level MMA functions such as HypothesisTestData
.
Here is the data of egreg's daily rep for the past 1460 days:

FindFormula
gives different outputs). But you used the last 90 values, while I took all 1460, so no wonder there's a difference. $\endgroup$ – corey979 Jan 5 '18 at 19:35FindFormula
gives me always 0 for $x>=1460$ so I can't reproduce your result. However I used all the data points in my approach and I found only 5 seconds difference with your result. The data is not as linear as it seems! $\endgroup$ – anderstood Jan 5 '18 at 19:49
