Extract Standard Errors of Model Coefficients

Extract standard errors of model coefficients from objects returned by count modeling functions.

Usage

se.coef(object, parm, type, ...)

# S3 method for class 'renewal'
se.coef(object, parm, type = c("asymptotic", "boot"), ...)

Arguments

object: an object returned by one of the count modeling functions.
parm: parameter's name or index.
type: type of standard error: asymtotic normal standard errors ("asymptotic") or bootsrap ("boot").
...: further arguments for methods.

Value

a named numeric vector

Details

The method for class "renewal" extracts standard errors of model coefficients from objects returned by renewal. When bootsrap standard error are requested, the function checks for the bootsrap sample in object. If it is not found, the bootsrap sample is created and a warning is issued. Users can choose between asymtotic normal standard errors (asymptotic) or bootsrap (boot).
