UncDecomp (version 1.0.1)

stage_uncertainty: Stage uncertainty(DEPRECATED)

Description

This function performs uncertainty decomposition by stage based on the second order interaction ANOVA model. The uncertainty from interaction effect from two stages is divided equally and assigned to each stage.

Usage

stage_uncertainty(data, var_name, stages = setdiff(names(data),
  var_name))

Arguments

data

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

var_name

the name of the variable of interest

stages

names of the stages in the model.

Value

List of 4 elements

summary

summary of uncertainties

main_uncer

a vector of uncertainties from the main effects of the stages

int_uncer

a vector of uncertainties from the interaction effects of the stages

scenario_uncer

a vector of uncertainties of the stages

Examples

# NOT RUN {
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)
data <- cbind(data, y)
