Value

Returns the type of residuals requested.

Arguments

# Reading in a dataset
data(mri)

# Create a uRegress object, regressing ldl on age
ldlReg <- regress("mean", age~ldl, data=mri)

# Get the studentized residuals
residuals(ldlReg, "studentized")

# Get the jackknifed residuals
residuals(ldlReg, "jackknife")
