Confidence Intervals for Covariate Coefficients
Description
confint,rateReg-method is an S4 class method for
rateReg object, which returns approximate confidence intervals
for all or specified covariates.
Usage
## S4 method for signature 'rateReg'
confint(object, parm, level = 0.95, ...)
Arguments
object |
A |
parm |
A specification of which parameters are to be given confidence intervals, either a vector of numbers or a vector of names. If missing, all parameters are considered. |
level |
An optional numeric value to specify the confidence level required. By default, the value is 0.95, which produces 95% confidence intervals. |
... |
Other arguments for future usage. |
Details
Under regularity condition (Shao 2003, Theorem 4.16 and Theorem 4.17, page 287, 290), the approximate confidence intervals are constructed loosely based on Fisher information matrix and estimates of coefficients.
Value
A numeric matrix with row names and column names.
