Hi Mr. Hardy-- I saw that you wrote an article on logistic curves. I'm trying to understand the difference between these 2 equations both of which are supposed to be s-curves (one being sigmoid).
Can somebody pls tell me what the difference is between these 2 s-curve equations? 1 / (1 + exp(a1x ^a2) ) or 1-exp(-c*x^d)
I am not a mathematician so I would appreciate a layman's explanation. Thank you for your help!
