confint.stdParfrailty function

Confidence interval

This is a confint method for class "stdParfrailty".

## S3 method for class 'stdParfrailty'
confint(object, parm, level = 0.95, fun, type="plain", ...)

Arguments

• object: an object of class "stdParfrailty".

• parm: not used.

• level: the coverage probability of the confidence intervals.

• fun: a function of one matrix argument with q rows and p columns, which returns a vector of length q.

• type: a string specifying the type of confidence interval; plain

  (for untransformed) or log (for log-transformed).

• ...: not used.

Details

confint.stdParfrailty extracts the est element from object, and inputs this to fun. It then uses the delta method to compute a confidence interval for the output of fun.

Returns

a matrix with q rows and 2 columns, containing the computed confidence interval.
