unc_postprocess: Postprocess UD

In UncDecomp: Uncertainty Decomposition

Description

ppud() adjusts uncertainty so that it is not less than a certain value. In particular, it is often used for UD_bal_model, where the uncertainty may be negative. min_lambda_calc() finds lambda such that the proportion of the minimum uncertainty is the specified value.

Usage

ppud(UD, lambda_list)

min_lambda_calc(UD, prop)

Arguments

UD	model-wise uncertainty or stage-wise uncertainty
lambda_list	a numeric vector that adjust the degree to which uncertainties and average uncertainty are close.
prop	target proportion of least uncertainty

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_model_var <- UD_bal_model(data, "y", stages, u_var, flist_var)
UD_bal_model_var
UD_bal_model_mad <- UD_bal_model(data, "y", stages, u_mad, flist_mad)
UD_bal_model_mad 
UD_bal_model_range <- UD_bal_model(data, "y", stages, u_range, flist_range)
UD_bal_model_range 

UD_bal_stage_var <- UD_model2stage(UD_bal_model_var)
UD_bal_stage_var 
UD_bal_stage_mad <- UD_model2stage(UD_bal_model_mad)
UD_bal_stage_mad 
UD_bal_stage_range <- UD_model2stage(UD_bal_model_range)
UD_bal_stage_range 

UD_list = ppud(UD_bal_model_range)
plot(UD_list)

lambda = min_lambda_calc(UD_bal_model_range, 0.01)
UD_1percent = ppud(UD_bal_model_range, lambda)
UD_1percent$UD[[1]]
