Classification of cases as typical and deviant using the standard deviation of the residuals.

The share of the standard deviation of the residuals is used to designate cases as typical or deviant.

Usage

Arguments

lmobject: Object generated with lm
stdshare: Share of standard deviation of residuals distinguishing between typical and deviant cases (default is 1).

Value

A dataframe with the observed outcome, fitted outcome, residual standard deviation and classification of cases as typical or deviant.
