The examples in these two chapters are designed for you to follow along with step by step to build our infrastructure and application. This closely emulates the real process of prototyping new infrastructure and is close to what I really do in my own development....

The well-known Akaike Information Criterion (AIC) cannot be directly applied since AIC is based on maximum likelihood estimation while GEE is nonlikelihood based. We propose a modification to AIC, where the likelihood is replaced by the quasi-likelihood and a proper adjustment is made for the ...
Assuming that the number of lags ranges from 1 to 4, we estimated all equations and used the Akaike Information Criterion (AIC) and Schwartz Criterion (SC) to determine the optimal (The combinations which minimize the AIC and SC.) solution defined as: Where W stands for estimated residual ...
Fit the model on (s1,s2,s3) using the complexity parameter obtained in step 1. Measure your performance on s4 Repeat the process for all folds. BIC/AIC/ CV/ LARS CV : These are the methods that the amount of regularization is determined. The difference between CV and ...
