Hi!

I am new to MatLab and I am trying to get the AIC, CAIC, SBC, and ICOMP for different distributions. Here is my code for the normal disturbution as an example (I have seven differnt distributions). I have already generated NLOGL1, PHAT1, AVAR1, and n.

[aic, caic, sbc, icomp] = fitscore(NLOGL1, PHAT1, AVAR1,n);

res_row = [aic, caic, sbc, icomp];

res = res_row;

However, I get this error: Unrecognized function or variable 'fitscore'.

Any ideas of why this could be happening? I have the curve fitting toolbox already so I know that isn't the issue.

Thank you!

Could you link to the documentation page for fitscore? I am unable to find a function with that name.

Hi Bethany,

The function ‘fitscore’ is not a MATLAB function. It is likely to be a user-defined function. Please ensure that the file with this function is on the MATLAB path before executing your code. This would eliminate the error (Unrecognized function or variable 'fitscore').

If this error continues to be reported, please post the relevant code here so I can dig deeper into it.

Regards,

Prateek.
