How can I use AIC and BIC in Matlab? Hello everybody! I am using the Curve Fitting Toolbox of Matlab to fit some non-linear models to my data, but I want to know which model fits better. This MATLAB function estimates the parameters of a nonlinear grey-box model, init_sys, using time-domain data, data.

The AIC and the BIC are two popular measures for comparing maximum likelihood models. AIC and BIC are deﬁned as AIC = 2 ln(likelihood)+2 k BIC = 2 ln(likelihood)+ln(N) k where k = number of parameters estimated N = number of observations We are going to discuss AIC along with BIC because AIC has some of the problems that BIC has, but not all. Akaike’s Information Criterion (AIC) How do we decide what variable to include? • AIC considers both the fit of the model and the number of parameters used – More parameters result in a penalty Hirotugu Akaike, 1927-2009 In the 1970s he used information theory to build a numerical equivalent of Occam's razor
