fitnlm - Infos on Family, Error Distribution, Link Function etc.

Dear all,

I have two metrical variables x and y (each size 30 x 1). I am using fitnlm to make a nonlinear regression between both.

modelfun = @(b,x)b(1) + b(2)*x(:,1).^b(3) + b(4)*x(:,1).^b(5);
beta0 = [1 1 1 1 2];
mdl = fitnlm(x,y,modelfun,beta0)

The fitting works fine and produces good results. However, I am not an expert in nonlinear regression. The reviewer of a paper has now asked me to be more precise when explaining the regression type I use. He asks me to specify:

- regression family - link function - error distribution

I am not able to answer him on this.

Can you please help me out?

Kind regards

Andreas
