stage_uncertainty: Stage uncertainty(DEPRECATED)

In UncDecomp: Uncertainty Decomposition

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

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)
# stage_uncertainty() is deprecated. Use UD_ANOVA_stage()
# stage_uncertainty(data,"y", names(data)[-4])
