why would you use the aic to test your model which model is the best to compare photoluminescence spectra using an aicc how many peaks is the aicc how do i compare two model to different one? what is the purpose of the aicc why use akaike's information criteria how does aicc compare to a similar fit? how to calculate the aicc how do you use a aicc to compare two different models? how many parameters in akaike's probability-function why is the aicc overparameterized how to use akiike's information criterion to compare two different models? can you compare two aicc models to get a normal distribution? what is the underlying error of each spectra what is an aicc what is the independent variable for the measurement and fitting of a multi-peaked spectra? what kind of error does aiks information criterion what are the underlying errors in akaike's information criterion? what is the underlying error of a model how many parameters does a aicc include
