confInt.OEFPIL {OEFPIL}

Confidence intervals for OEFPIL parameters

Description

Function computes confidence intervals for the parameters counted by OEFPIL function.

Usage

confInt.OEFPIL(object, signif.level = object$contents$signif.level, parm)

Arguments

object

an object of class "OEFPIL" (a result of a call to OEFPIL).

signif.level

a numerical value or a vector of significance levels for confidence intervals. If missing, a value from the input "OEFPIL" object is used.

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.

Details

The confidence intervals are computing under normality assumption.

Value

A matrix of estimated confidence intervals for model coefficients from an "OEFPIL" object. The matrix contains lower and upper confidence limits (columns) for each parameter (rows).

Examples

##-- Continuing the coef.OEFPIL(.) example:

##Use of confint function
#one numerical value
confInt.OEFPIL(st1)

#vector of numerical values
confInt.OEFPIL(st1, signif.level = c(0.01,0.05,0.1))

#estimation of specified parameters
confInt.OEFPIL(st1 , signif.level = c(0.01,0.05,0.1), parm = c('b1','b2'))
