In robcbi: Conditionally Unbiased Bounded Influence Estimates

Print methods for objects of class "cubinf", "cubinf.i", "summary.cubinf" or "glm.i"

Description

Printing linear model fits provided by glm or with method="cubinf"

Usage

## S3 method for class 'cubinf'
print(x, ai = FALSE, ci = FALSE, A.mat = FALSE, ...)

## S3 method for class 'summary.cubinf'
print(x, ...)

## S3 method for class 'glm.i'
print(x, ...)

Arguments

x	An object result of a call to summary.cubinf (first usage), to glm with method="cubinf" (second usage), to rscale.cubinf or to summary.cubinf or to weights.cubinf or to covar.cubinf (third usage) and respectively to rscale.glm or or to covar.glm or to weights.glm.
ai	Vector with components a_i=ufact/|Ax_i| (where x_i^T denotes the ith row of the model matrix).
ci	Vector of the final bias corrections.
A.mat	The final value of the matrix A.
...	Further optional arguments according to the print method. Implicit argument in all these functions is digits = max(3, .Options$digits - 3).
