| vcov.singleRStaticCountData {singleRcapture} | R Documentation |
Obtain Covariance Matrix estimation.
Description
A vcov method for singleRStaticCountData class.
Usage
## S3 method for class 'singleRStaticCountData'
vcov(object, type = c("Fisher", "observedInform"), ...)
Arguments
object |
object of singleRStaticCountData class. |
type |
type of estimate for covariance matrix for now either expected (Fisher) information matrix or observed information matrix. |
... |
additional arguments for method functions |
Details
Returns a estimated covariance matrix for model coefficients
calculated from analytic hessian or Fisher information matrix usually
utilizing asymptotic effectiveness of maximum likelihood estimates.
Covariance type is taken from control parameter that have been provided
on call that created object if arguments type was not specified.
Value
A covariance matrix for fitted coefficients, rows and columns of which
correspond to parameters returned by coef method.
