UD_bal_stage {UncDecomp}

Stage-wise balanced uncertainty

Description

This function performs the balanced uncertainty decomposition. In balanced uncertainty decomposition, we assume that the total uncertainty decomposes into the uncertainty of all main effects and all orders of interaction between stages. This method distributes the uncertainties of each element evenly among the associated stages.

Usage

UD_bal_stage(data, var_name, stages, U = U_var)

Arguments

data

a data frame containing models(factor or character) for each stages and the variable of interest(numeric). data should contain all combinations of models.

var_name

the name of the variable of interest

stages

names of the stages of interest.

U

a function that returns uncertainty such as range and variance of a given numeric vector. This package have built-in uncertainty functions U_var(), U_mad() and U_range(). Default is U_var().

Value

stage-wise uncertainties(UD_stage class)

Examples

set.seed(0)
stage1 <- LETTERS[1:3]
stage2 <- LETTERS[1:2]
stage3 <- LETTERS[1:4]
y <- rnorm(3*2*4)
data <- expand.grid(stage1=stage1,
                    stage2=stage2,
                    stage3=stage3)
stages <- names(data)
data <- cbind(data, y)
UD_bal_stage(data, "y", stages, U_var)
UD_bal_stage(data, "y", stages, U_mad)
UD_bal_stage(data, "y", stages, U_range)
