vcov.logbin: Calculate Variance-Covariance Matrix for a Fitted logbin Model Object

Description

Returns the variance-covariance matrix of the main parameters of a fitted logbin model object.

Usage

# S3 method for logbin
vcov(object, ...)

Arguments

object

an object of class "logbin", usually from a call to logbin or logbin.smooth.

…

additional arguments for method functions.

Value

A matrix of the estimated covariances between the parameter estimates in the linear or non-linear predictor of the model. This should have row and column names corresponding to the parameter names given by the coef method.

Details

An equivalent method to vcov, to use with logbin models.
