Liu Regression Residuals
Description
The residuals function computes the Liu residuals for scalar or vector value of biasing parameter d.
Usage
## S3 method for class 'liu'
residuals(object, ...)Arguments
object |
An object of class "liu". |
... |
Not presently used in this implementation. |
Details
The generic functions residuals can be used to compute residuals of object of class "liu" from function liu.
Value
Returns a vector or a matrix of the Liu residuals for scalar or vector value biasing parameter d provided as argument to liu function.
