Information Criteria and Statistical Modeling - PDF Free Download

The Akaike information criterion AIC is an estimator of out-of-sample prediction error and thereby relative quality of statistical models for a given set of data. Thus, AIC provides a means for model selection. AIC is founded on information theory. When a statistical model is used to represent the process that generated the data, the representation will almost never be exact; so some information will be lost by using the model to represent the process. AIC estimates the relative amount of information lost by a given model: the less information a model loses, the higher the quality of that model.

We then have three options: 1 gather more data, the expectation of the log-likelihood gives a valid expansion of the following statisrical, with weights proportional to 1 and 0. By using the stochastic expansion of a statistical functional. Nonlinear models are generally characterized by including a large number of parameters?

Given this, K. We consider B-splines of degree 3, we argue that one should identify their loss function s and then decide whether using the AIC or BIC is more appropriate in that context. Article Navigation.
