Non linear regression

[Adelodun]

How do i get the coefficients in:

C = H exp [- (bo + b1A^-1) D/H]

Thank you.

Start by looking at the documentation and examples for PROC NLIN

Examples of PROC NLIN: https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.3/statug/statug_nlin_examples.htm

Can C take negative values? If not then maybe you should be fitting the Log of C, in which case you would be fitting a linear equation (with proc reg, for example).
