Time of peak of an SIR epidemic
Seems like you fell in love with those equations and, especially, with the $I$ component of them:-). So let me try to show you how you can derive as many approximations as you want yourself, test them …

Approximated solutions of SEIR models
Is your function F(x) known for giving good fits in many contexts? How can these be characterized?
This is too long for a comment but I'd like you to check if the fit is to your satisfaction before I …

Removing outliers from circular average data
An alternative approach is just to choose some real trigonometric polynomial $p(x)=\sum_{k=-m}^m c_ke^{ikx}$ that is like $ct^2$ near the origin and like $1$ far from it and to minimize $q(x)=\sum_j p …

Recovering a function from a set of approximations
This is a bit too long for a comment, so I post it as an "answer".
Let us crunch your numbers a bit. Suppose you just have 100 bad agents and use the simple majority rule. Then, on an easy value, the …
