Description Usage Arguments Value Examples
This function performs uncertainty decomposition based on the cumulative uncertainty.
1 2 |
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 in the modeling chain. should be ordered by the order of the modeling chain |
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(). |
stage-wise uncertainties(UD_stage class)
