Extract Components of a Fit

Description

Retrieve the table of coefficients and standard errors, or the scale parameter, or the factors needed for standardizing coefficients from diverse model fitting results

Usage

getcoeftable(object)
getscalepar(object)
getcoeffactor(object, standardize = TRUE)

Arguments

object	an R object resulting from a model fitting function
standardize	ligical: should a scaling factor for the response variable be determined (calling getscalepar) and used?

Details

Object regrModelClasses contains the names of the classes for which the result should work. For other model classes, the function is not tested and may fail.

Value

For getcoeftable: Matrix containing at least the two columns containing the estimated coefficients (first column) and the standard errors (second column).

For getscalepar: scale parameter.

For getcoeffactor: vector of multiplicative factors, with attributes scale, fitclass and family or dist according to object.

Examples

  rr <- lm(Fertility ~ . , data = swiss)
  getcoeftable(rr) # identical to  coef(summary(rr))  or also summary(rr)$coefficients
  getscalepar(rr)

 if(requireNamespace("survival", quietly=TRUE)) {
  data(ovarian) ## , package="survival"
  rs <- survival::survreg(survival::Surv(futime, fustat) ~ ecog.ps + rx,
                data = ovarian, dist = "weibull")
  getcoeftable(rs)
  getcoeffactor(rs)
 }
