Hi I have a homework question that I just don't think I have the formula right.

Question: The logistic equation is commonly used to model growth phenomena in biological populations: Y = (L/(1+e^-a(x-b)), where Y is the response, x is the input, L, a, and b are constants. Assume that L is given as Lo, find the least squares estimations of a and b.
