confint.IHA: Confidence Intervals for IHA Central Tendencies

In mkoohafkan/flowregime: Environmental Flow Regime Indicators

Description

Computes confidence intervals for parametric and non-parametric central tendencies computed by IHA.

Usage

## S3 method for class 'IHA'
confint(object, parm, level = 0.95, ...)

Arguments

object	An object of class IHA.
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	The confidence level required.
...	additional argument(s) for methods.

Details

Parametric confidence intervals are computed using t-test. Non-parametric confidence intervals are based on parameter value rankings.

Value

A matrix (or vector) with columns giving lower and upper confidence limits for each parameter. These will be labelled as (1 - level)/2 and 1 - (1 - level)/2 in

Examples

data(siouxcity)
res = IHA(siouxcity['2009/2011'], ut = 32000, lt = 12000)
summary(res)
confint(res)
