se.coef {Countr}

Extract Standard Errors of Model Coefficients

Description

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.

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).

Value

a named numeric vector
