residuals.selection: Residuals of Selection Models

Description

Calculate residuals of sample selection models

Usage

## S3 method for class 'selection':
residuals(object, part = "outcome",
   type = "deviance", ... )

Arguments

object

object of class selection.

part

character string indication which residuals to extract: "outcome" for the fitted values of the outcome equation(s) or "selection" for the fitted values of the selection equation.

type

the type of residuals of the selection equation. The alternatives are: "deviance" (default), "pearson", and "response" (see residuals.probit).

...

further arguments passed to other methods (e.g. residuals.probit or residuals).

Value

• A numeric vector of the residuals.

Details

The calculation of the fitted values that are used to calculate the residuals is described in the details section of the documentation of fitted.selection.
