coef.outference: Extract coefficients from an '"outference"' object

In shuxiaoc/outference: Valid Inference in Linear Regression Corrected for Outlier Removal

Description

This function extracts the estimated regression coefficients from an "outference" object.

Usage

## S3 method for class 'outference'
coef(object, model = c("removed", "original"), ...)

Arguments

object,	an object of class "outference".
model,	if model = "removed", then the coefficients are from the fit with outliers removed; if model = "original", then the coefficients are from the fit with all the data.
...,	other arguments.

Value

This function returns the desired vector of regression coefficients.

Examples

## Brownlee’s Stack Loss Plant Data
data("stackloss")
## fit the model
## detect outlier using Cook's distance with cutoff = 4
fit <- outference(stack.loss ~ ., data = stackloss, method = "cook", cutoff = 4)
coef(fit, model = "original")    # the coefficients from the fit using all the data
coef(fit, model = "removed")     # the coefficients from the fit after outlier removal
