icfit-class function

Class "icfit"

Stores the output of the search for the model with best information criterion value, e.g. produced by bestBIC, bestBIC, bestAIC or bestIC. The class extends a list, so all usual methods for lists also work for icfit objects, e.g. accessing elements, retrieving names etc.

Methods are provided to extract coefficients, predictions, confidence intervals and summary information about the best model. 1.1

class

Objects from the Class

icfit objects are automatically created by a call to bestBIC or similar.

Slots

The class extends a list with elements:

• topmodel: names of the variables in the top model
• topmodel.fit: top model as fitted by glm
• models: data frame with the information criterion for all models (when enumeration is feasible) or those visited by an MCMC model search in modelSelection (when enumeration is not feasible)
• varnames: the names of all variables in the design matrix
• msfit: Output of modelSelection (used to search the top model)

Methods

• coef: glm fit for the top model
• confint: Confidence intervals under the top model
• predict: Predictions for the top model (predict.glm)
• show: signature(object = "icfit"): Displays general information about the object.
