The Akaike information criterion (AIC) is an estimator of prediction error and thereby relative quality of statistical models for a given set of data. Given a collection of models for the data, AIC estimates the quality of each model, relative to each of the other models. Thus, AIC provides a means for model selection.

Note that the \scale" parameter is presented as the Root MSE in the output. The regress syntax is shown next: regress loghinc reached by FPE and AIC C, which of course know nothing of the above considerations. Table I gives p, SSE, R2, FPE and AIC C for l m the 8 candidate models. For the polynomia odels, SSE decreases and R2 increases with p,as, a expected, FPE selects a 6’th degree polynomial nd … Description. Build regression model from a set of candidate predictor variables by entering predictors based on akaike information criterion, in a stepwise manner until there is … You can simply extract some criteria of the model fitting, for example, Residual deviance (equivalent to SSE in linear regression model), AIC and BIC. Unlike linear regression models, there is no \(R^2\) in logistic regression.

More specifically, I have: MODEL 1 regress log_spread a b c X estat ic which gives AIC = 915 then, MODEL 2 regress log_spread a b c estat ic which gives AIC = 1500. but the OLS in model 1 uses 1200 observations while the OLS in model 2 uses 2800 observations (because 1600 observations are missing in variable X)!!

It generates a weird AIC value. I tried running analyse > regression > binary logistic and run the same model "regress response on predictor A". In the output I got -2Loglikehood and plug it into the AIC formula "AIC= -2Loglikehood +2p".

On http://www.r-bloggers.com/how-to-perform-a-logistic-regression-in-r/ the AIC is 727.39.

Both criteria depend on the maximized value of the likelihood function L for the estimated model. When we fit a multiple regression model, we use the p -value in the ANOVA table to determine whether the model, as a whole, is significant. A natural next question to ask is which predictors, among a larger set of all potential predictors, are important. We could use the individual p -values and refit the model with only significant terms. Stata has two versions of AIC statistics, one used with -glm- and another -estat ic- The -estat ic- version does not adjust the log-likelihood and penalty term by the number of observations in the model, whereas the version used in -glm- does.
