Extract Residuals from a SIR Model — residuals.sir • sir

Returns residuals of the specified type. Response residuals are raw (Y - fitted). Pearson residuals are standardized by the variance function. Deviance residuals are signed square roots of the individual deviance contributions and are most useful for diagnostic plots.

Usage

# S3 method for class 'sir'
residuals(object, type = c("deviance", "pearson", "response"), ...)

Arguments

object: A fitted sir object from sir.
type: Character string specifying residual type: "deviance" (default), "pearson", or "response".
...: Additional arguments (unused).

Value

An array with the same dimensions as Y containing the requested residuals. Contains NA where Y is missing.
