methods-residuals: Extract Model Residuals.

In modelObj: A Model Object Framework for Regression Analysis

Description

Returns the residuals from an object of class modelObjFit.

Usage

 ## S4 method for signature 'modelObjFit'
residuals(object, ...) 

Arguments

object	an object of class modelObjFit containing the regression object from which residuals are to be retrieved.
...	ignored

Value

If residuals() is defined for the regression method used to obtain parameter estimate, returns the residuals as defined by the regression method. If method does not exist, a warning messages is printed.

Examples

    #----------------------------------------------------#
    # Generate data
    #----------------------------------------------------#
    X <- matrix(rnorm(1000,0,1),
                ncol=4,
                dimnames=list(NULL,c("X1","X2","X3","X4")))

    Y <- X %*% c(0.1, 0.2, 0.3, 0.4) + rnorm(250)

    X <- data.frame(X)

    #----------------------------------------------------#
    # Create modeling object using a formula
    #----------------------------------------------------#
    mo <- buildModelObj(model = Y ~ X1 + X2 + X3 + X4,
                        solver.method = 'lm')

    #----------------------------------------------------#
    # Fit model
    #----------------------------------------------------#
    fit.obj <- fit(object=mo, data=X, response=Y)

    res <- residuals(fit.obj)
    head(res)
