Currently, I'm inputting the initial guess manually. But I was trying to find a automated way of guessing the initial parameters, after the X & Y inputs are received from the user.
I'm trying to solve Weibull model : y = a-b*exp(-cx^d)
Everything works fine (till now :)), but the initial guessing needs to be entered manually. But I found
this software doing the initial guessing automatically based on the X & Y input values :
