*DATASET GET SOBOL*
===================

Computes Sobol sensitivity indices for a dataset, quantifying how much variance in each target output is attributable to each input variable. Use this worker when you need variance-based global sensitivity analysis to rank the influence of input parameters on simulation or experimental responses.

When to use

Inputs

   * - Label

     - Default
     - Required
     - Description
   * - Dataset
     - dataset
     - dataset
     - —
     - 
     - Input dataset containing both the input variables and target response columns; all rows are used for the Sobol index estimation.
   * - Inputs
     - inputs
     - scalar
     - —
     - 
     - One or more column names from the dataset to treat as input (independent) variables for the sensitivity analysis; select all parameters whose influence you want to quantify.
   * - Targets
     - targets
     - scalar
     - —
     - 
     - One or more column names from the dataset to treat as output (response) variables whose variance will be decomposed into Sobol indices.
   * - Number Of Sampling
     - num_sampling
     - scalar
     - 10000
     - 
     - Number of Monte Carlo samples used internally to estimate the Sobol indices; defaults to 10 000 — increase for higher accuracy at the cost of compute time.
