Maureen Efenovwe For what purpose may I ask? If you need it for simple nonlinear regression for instance Michaelis-Menten free version software such as Kyplot can be used. Or you can try Excel with Solver add in for nonlinear regression.

see

for more than two-parameter nonlinear regression works you can try kyplot but you need to know how to design the software-friendly equation

for instance, the three-parameter (P1,2 and 3) Redlich-Peterson isotherm, you need to use the following equation

y=P1*x/(1+P2*(x**P3))

@Bhairavi vajaria. I need it to calculate ELISA standard concentration, I'm not sure I can use SPSS for that

Maureen Efenovwe ELISA uses 4 parameter logistics equation for nonlinear regression.

for free 4-PL software for ELISA try and learn
